Thank u so much I was tired searching about it since long and finally got this exact thing
Me also bhai
He has covered all the advanced topics with such an impeccable quality of teaching
really nice video in that it covered it from basics - i had only memorised it, but thanks for going in details without all the jargons and hype that other coaching institutes create
sir please organize your videos, it's a humble request
head over to the site mentioned in the descriptions - there, the videos are verry well organised
Fricking hell.. this is JEE Advanced level content right there, cleared all my doubts which i had on this topic! TYSM!
Tho i may have a doubt, is it possible to calculate the electric field's *value* inside the cavity? I think not, but i am not sure
E=0 inside the cavity. Sir said in the video
By taking gaussian surface as any spherical surface inside the solid sphere, electrostatic force inside gaussian surface is zero. Thus electric field =0.
Refer 3:20 for more info
@@badpineapple9120 i am not saying inside the conductor, but the empty part between the charge and conductor
the field inside the cavity originates due to the positive charge, which means at any point the field is Kq/r^2 inside the cavity until you enter the conductor
@@badpineapple9120 you got it mixed up
the field inside a cavity is due to the positive point charge only, which is equal to Kq/r^2 at a distance r from the charge as long as you are outside the metal shell
Much precise, detailed and well explained than most of the videos out there on the same topic.
your videos clear doubts instantly! keep em coming.
Had tears (of happiness) finally I got it sir. I love how you raise questions and tell us to think about it. ❤ Amazing teaching 👏🏻 stay blessed
Why I didn't know this channel before??
The video is so clear and easy to understand!!! Thank you very much
outstanding work, talking as a physics teacher
Physics always leaves me speechless 💯
Literally terrific explanation
Wow extremely clear explanation. The only video i found that covers this topic in depth.
Thank you….I was searching this for a long…I always used to get confused and even no one has explained this concept….finally the concepts are clear!!
The charge distribution on the outer surface doesn't depend on the charge distribution on inner surface so outer charge distribution must be uniform
How'd he get the cursor to have two fingers pointed out :0
Explanation can be to the point and not take longer time
This result is remarkable. I remember seeing this in Physics class but as usual throwing out all the amazement.
thanks a lot
I am grateful to you sir❤
Your explanation is very helpful...thankyou so much🤗
Sir excellent sir, organize your videos sir
Such a nice explanation, I couldn't even understand a single thing by reading my text book for the 5th time....Now everything is clear.
Thnku sooo much sir nd hatts of to your commendable teachingg
You are one of the greatest teacher
I fell in love with your video every time
great video! We need more educators like you
you're a lifesaver thank you
Thank you sir
Amazing video! Thanks from Portugal
Really 😶😶😶
Best explanation
Thanks
Outstanding amazing mind blowing sir
I am so much confused about this topic but thank u so much for solving my doubt🤩
Mazza aaya!
THANK YOU!
Really got a charge out of the lecture, you have great energy.
Superb
Thanks it helped a lot
What if the sphere is grounded, would it have the same results? Please answer as soon as possible, Ty
thnks sir
Thankyou
Thankyouu
LOVE FROM UGANDA KI KALIGHATI 😌🔥
Mahn ur just too gud pls continue this good work
Also positive charges are immobile in a solid conductor
Nice explanation
but what if the charge is placed at the centre then the negative charges would be uniform right??
Hi. I like your videos. I’m following a electromagnetism and I think that this problem (which is the Faraday ice pail) explain together different properties. As a person that is learning I don’t feel that your explanation when you say that the “outside word” is disconnected from the inside because you can imagine a Gaussian surface and so there is no flux through is the best explanation.. don’t get me wrong you can explain with Gauss law but I would try to give a different explanation without Gaus law of why outside there is not other option than uniformely distribution charge..
will there be any charge induced on the outer surface of the cavity?
hush finally my doubt is solved
Sir will you cover capacitor and capacitance also.?
Simply awesome. Please create more such videos on difficult concepts.
Hi, does that means I have a field equal to the resonance field outside of the room (faraday cage) but more scattered ?
How the positive charges are supposed to gather around the conductor if there's no electric field in-between them or they're disconnected from the inner postive charge? Can someone clarify this?
Thank u providing us quality education bro
A spherical conducting shell, centered at the origin, has inner radius a and outer radius
b. Its net charge is zero. Inside the shell, on the x-axis at at x = a/2 there is a point
charge q.
Which will be the direction and magnitude of the electric force acting on the point
charge?
So what is the field inside the cavity?
Zero
In case of neutral dielectric sphere wht happen??
Sir i have a doubt, let's say the cavity is of an irregular shape then the charge distribution on the surface of cavity will depend upon the position of point charge inside the cavity or on the local radius of curvature of the cavity ?
Depends on the position of charge inside the cavity otherwise electric field won't be zero
Centre of charge of non uniformly induced charges (-q ) on surface of cavity will lie on the charge (+q) inside the cavity (off centre here) so that E=O inside the material of the conductor
Is the charge on outer surface same as in centre or Different?
It has to be same
First thing, if you can come up with some argument that doesn't relay on gauss's law ?
2. You showed fields lines inside cavity that doesn't support the intuition that the net effect of these lines will be zero. If you can explain this any further.
did you find the answer? Im confused too
The electric field inside the conductor should be zero but doesnt the field lines between the charge q and induced negative charge indicate an electric field??
Such a Nice voice😂😊
❤❤❤❤❤❤❤❤🎉🎉🎉🎉🎉
Explanation is everything good....but while listening into another English accent feeling difficult to hear....
😡🤬
It's probably the laziest video you ever made
Avoid that cheap accent 🙏
Thanks a lot
Thanks a lot
