Sir, what is the difference between orbital angular momentum and azimuthal quantum number (NCERT says both are the same thing)? But the formula for the orbital angular momentum is √l(l+1) h/2π..... Also, According to Bohr's model the electron moves in a circular orbit. So, it is quite clear that it will have some orbit angular momentum, But, what exactly is the orbital or spin angular momentum? is it related to the revolution of the electron, or something else?
Bro, Earth has a spin agnular momentum due to its rotation around its axis, this is equal to "(Moment of inertia of the earth around its axis) × (Earth's angular velocity about that axis)". Earth also has a Orbital angular momentum due to its motion around the sun, the value of this Angular momentum is subject to the chosen origin. Hence the total Angular momentum of earth is the sum of these two.(WE HAVE TWO TYPES OF ANGULAR MOMENTA BECAUSE EARTH IS AN EXTENDED BODY AND NOT A PARTICLE IF IT WERE A PARTICLE, WOULD WOULD only have ORBITAL ANGULAR MOMENTUM).Similarly An electron also has 2 types of Angular Momenta.

We do line integral of electric field around a conducting loop having varying magnetic flux through it to find the emf in that coil caused by the varying magnetic field. But doing integral over the loop suggests that the electric field is distributed over the circular loop. Question :: Wouldn't it mean a electric field which is circular in direction exists ?
when the conducting wire forms closed loop then a current will flow due to the emf generated.......and so its obvious that electric field will be along the alignment of conducting wire........but when ever there is static charge at one point then the electric field is radial.

Hello sir, this is pradyumn porwal currently studying in NIT Warangal .I have one doubt since i was preparing for my jee exam.doubt is from your book's question only. Question is: A table with smooth horizontal surface is turning at an angular speed o about its axis. A groove is made on the surface along a radius and a particle is gently placed inside the groove at a distance a from the centre. Find the speed of the particle as its distance from the centre becomes L. Sir in this question if we try to observe in ground frame ,then which force is responsible for taking particle outside.sir I am stuck in this problem from last 4 years. I remember when I used to ask my faculty they used to say do it by Taking the reference of table .sir please help me in this question.
Normal reaction by the groove has 2 components. One is vertically upwards (which balances mg) and the other is along the surface of the table (perpendicular to the line of groove). And this very component is responsible for the ball to move away from the centre. U just draw the diagram for 2 consecutive instants. For the first instant , normal provides velocity perpendicular to the line of groove. At 2nd instant, line of groove turns by an angle, and intial velocity attained by the ball is now at some angle with the line of groove. Now the normal has no control over the component of velocity along the line of groove, due to which ball moves outwards.
It's just a convention, to aid us in visualisation. Look at it this way: We have defined electric field due to positive and negative charges and can show them in diagrams, but we take the test charge to be positive( the unit charge) so it would feel a repulsion by positive charge so electric field is away from it to show that a unit positive charge would feel the force this way and for negative it is the other way in similar manner. If we had choosen the unit test charge to be negative then field line would go from negative to positive instead... and if you are asking why the field lines go from positive to negative then you can think of it as the attraction and repulsion of a positive charge in between..
matter of naming it positive or negative is purely arbitrary, the main thing is whether it is charged or not, that you can check using some paper peices, plastic scale will attract small peices of paper, or you can use an electroscope as some other fellow also commented
To know whether the scale is sufficiently charged or not just bring some very small pieces of paper near it . If the pieces are attracted to the scale that means the scale is sufficiently charged. To know what kind of charge is on the scale we can use electroscope but for this we must have known source of +ve or -ve charge otherwise we couldn't understand what type of charge is on scale. There is an other way , if you know the material properties of the objects you rub with each other ,you will know the type of charge. From the atoms on surface of the objects of two type, in which electrons are comparatively loosely bound to atom that object will loose electrons and gets positively charged the other gets negatively charged.
Its easy from F=G (M1 M2)/R^2 ......SO V=ROOT(2GM/R)....M IS MASS OF OBJECT FOR WHICH SCWHARZSCHILD RADIUS IS TO BE CALC........PUT V=C(SPEED OF LIGHT)....THEN R IS THE REQUIRED RADIUS

Sir I am Aditya and I have a question that how can be say that a ball is moving in Space where there is no start and planet as there nothing to compare? Sir plzzz tell the answer, I searched it every where even on Google but didn't get the satisfying answer.....🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Shailesh Kumar Singh, exactly, you cannot say whether a ball in space is moving or not, unless you compare it with some other object. Motion is not absolute but rather relative. That means one object can be said to be in motion w.r.t one frame of reference and simultaneously be at rest w.r.t another frame of reference. Nothing in this whole universe is in absolute motion or rest. It is in motion or at rest only relative to another object.

Sir, I have a question..
Why electric field lines goes from positive to negative???? 🤔🤔
It's just an hypothesis 😁
It's just a convention, to aid us in visualisation. Look at it this way:
We have defined electric field due to positive and negative charges and can show them in diagrams, but we take the test charge to be positive( the unit charge) so it would feel a repulsion by positive charge so electric field is away from it to show that a unit positive charge would feel the force this way and for negative it is the other way in similar manner. If we had choosen the unit test charge to be negative then field line would go from negative to positive instead...
and if you are asking why the field lines go from positive to negative then you can think of it as the attraction and repulsion of a positive charge in between..
It's a convention
The answer is that they don't. (In reality)
sir could you please explain how the reflection and refraction takes place in spherical lenses ? Please sir.
Concave and convex lens?
@@chandrahasreddy1729 yes
Sir , it can only be explored by you sir ,
Thank very much
sir ka explanation is a competition to the rainbow's beauty.

Sir, I have a question.
We know that speed of light is 3 into 10 ^8 mps but sir how is it possible to measure it?
Thanks sir
Actually wecanot measure one way (watch vertasium vedio you tube chanel)
@@saumyaaaaaaaaaaaaaaaaaaaaa or that wheel experiment too. It doesn't gives the exact speed but yeah approximate value (i.e., 3*10^8 m/s)
ua-cam.com/video/pTn6Ewhb27k/v-deo.html
explains most of it
@@mephisto4618 no brother this video is just about theory that we don't know the one way speed of light.
We can use speed = distance / time formula...😅😅
Now, I get to know the right observation....Heartly Thank You sir,

Sir,when we rub plastic scale to our hair then how do understand that the scale is charged??? And Which charge (+ve or -ve) has the scale gained?????
Because of free electrons and electrons have negative charge.
How to know whether the scale is positively charged or negatively charged after rubbing?
To know this We use electroscope .
matter of naming it positive or negative is purely arbitrary, the main thing is whether it is charged or not, that you can check using some paper peices, plastic scale will attract small peices of paper, or you can use an electroscope as some other fellow also commented
Just its charged, we don't want it is positive charged or negatively charged.
To know whether the scale is sufficiently charged or not just bring some very small pieces of paper near it . If the pieces are attracted to the scale that means the scale is sufficiently charged.
To know what kind of charge is on the scale we can use electroscope but for this we must have known source of +ve or -ve charge otherwise we couldn't understand what type of charge is on scale.
There is an other way , if you know the material properties of the objects you rub with each other ,you will know the type of charge. From the atoms on surface of the objects of two type, in which electrons are comparatively loosely bound to atom that object will loose electrons and gets positively charged the other gets negatively charged.
Sir ,my question is-
Why does a clockwise rotating tennis ball after bouncing back from ground rotates anticlockwise.
From Magnus effect
Due to Impulsive force(friction) the tennis ball fells an torque in anticlockwise direction.👍
What a great explanation!! Sir..
I don't why people dislikes for the legends lecture 🙏🏻🙏🏻
Sir A question
How to calculate The Schwarzschild radius of any object
Plsssssssss
Its easy from F=G (M1 M2)/R^2 ......SO V=ROOT(2GM/R)....M IS MASS OF OBJECT FOR WHICH SCWHARZSCHILD RADIUS IS TO BE CALC........PUT V=C(SPEED OF LIGHT)....THEN R IS THE REQUIRED RADIUS
@@ayushranjan6116 please brother tell me how to make comand on physics from basics🙏 if u able please tell
@@ybl456 if you really love physics...then a little hard work will help u...but if u dont love it then its gonna be too hard....one should have a grip of calculus and basic concepts behind any phenomena to master physics
God of physics
Positivity radiates from you sir, this just made my day. Had to study Physics today but wasn't feeling like it, this just gave me a kickstart.
sir id ask similar doubts in my classes but teachers would either mock me or say its not necessary which made me lose interest in physics but sir thanks to you im regaining my interest
Fact: Sir is the backbone of JEE Aspirants.
nhi
Fun Fact: The dislike came from the students failed in Physics 😄😄
Brother you were shy to ask out that question to your teacher, see!!! one of the best Gurus made you understand ❤
Thank you sir for your explanation as I have read this in many places but can't understand. But your smiley explanation to this concept make this question too easy. Thank you so much sir
Sir I am Aditya and I have a question that how can be say that a ball is moving in Space where there is no start and planet as there nothing to compare? Sir plzzz tell the answer, I searched it every where even on Google but didn't get the satisfying answer.....🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Shailesh Kumar Singh, exactly, you cannot say whether a ball in space is moving or not, unless you compare it with some other object. Motion is not absolute but rather relative. That means one object can be said to be in motion w.r.t one frame of reference and simultaneously be at rest w.r.t another frame of reference. Nothing in this whole universe is in absolute motion or rest. It is in motion or at rest only relative to another object.
Sir, mera ek doubt he
Why light bends during refraction?
This concept is highly explained In NCERT.
By using wave theory of light you can understand it very simply
Sir has already made a video on this
@@hgawdomaa3426 ok thank you😊👍
@@hgawdomaa3426 maine o video dekha par car vala explanation tik se explain nahi kar raha quki light is electromagnetic wave hai va to electric field aur magnetic field se banati he aur uska mass bhi nahi to vo friction se slow bi nahi hogi
Mera abi doubt clear nahi huva
🤔🤔
My Science Teacher Has Shared This Video.And Your Explanation Is Very Interesting Sir.
India needs more passionate teachers like hcv sir.
