I'm not from India, but from northern Europe. And I must say your videos are absolutely fantastic. Your explanations are so clear and thought out, and the production quality is off the charts mate. Teaching is truly your calling, and I hope that you will Keep on producing as much as you're able. Kudos.Great!
Im from Brazil and i must say, i was struggling to learn this but your explanation was so clear... this is by far the best video i found, you should be proud of your skills
North or South , East or West two things are common which are doubts in physics and appreciating the teacher who came with an apt presentation and explanation to clear the doubts....marvellous video
i agree alakh sir teaches awesome but, i have forgotten his contents many times, but sir watched your videos, my mind forgot to forget :), concepts get more closer to heart , thank you sir
sir I'm not from India, some of my Indian friends (from delhi) have suggested your channel ,I'm thankful for what u explained , I wasted lot of money in online courses, now I'm gaining knowledge by your channel
I think your the best teacher out there, you went through every detail that my lecturer didint make clear , I watched alot of other videos , but none of them as clear as urs , thanks man
@@dropperhoonmein good question thanks for asking :) I’m not very familiar with the Indian high school system but in most cases I would say no, I think most Indian high-school goes further. That said subjects like integration and differentiation which seem to be commonly taught in Indian high schools. Are only seen in American high-school if you take optional “AP” or “IB” classes. So in mostly cases likely Indian students go more in-depth yet you’ll certainly have quite a few American students that are matching if not ahead of those Indian students. All that said, I’m not completely sure! Let me know what your experience was like if you went to school in India.
@@carterschuller1583 First of all thanks for the reply, I completed my high school in 2023 and took a drop year for my prep for competitive exams for college and as you said here high school calculus is very tough and the level of calculus, geometry and algebra in competitive exams ( like JEE ) is way beyond tough, but the worst part is even after going though this tough syllabus and these highly competitive exams I dono why our country has high unemployable graduates.

You give expanation to every single argument that comes into my mind . Whenever i watch your videos i feel so so happy . Thankyou so much for making such wonderful videos and for making our concepts crystal clear. Whenever i am confused in some topic i just type the topic and then khan academy . THANK YOU SIR 😌
......our teacher suggest to watch this video.... And I was surprised why he did so... But now after watching it I come to know.... U r simply amazing and so do your teaching style... ❤❤❤❤lots of love
Hello sir please make an NEET exam crash course because the exam is approaching and please make a crash course and give a handful of tricks and tips and hints to Solve the physics questions also to crack NEET exam so please so please give a handful of tricks tips and hints the Solve the physics questions of NEET exam
thanks a lot for being in ur true accent - this helped me to stay focussed and didnt distract me. (context: the copied/forced accent in other/older videos was very distracting for me)
I've been trying to look for a rigorous vector calculation. Using Gauss's law is contingent on the fact that you already *know* the direction of the field lines due to the infinite plane of uniform charge density. Using E = k integral(dq/r^2)r^, I want to *show* that the unit vector (r^) ends up in the positive z direction (assuming the plane lies along the x-y plane) for points above the plane, and in the negative z direction for points below the plane.
That explanation is pretty dope .. but it's Lil bit complicated insted of doing this ... You can imagine it as a rod and try to calculate it it'll be much easier
To calculate flux through a surface, we have to take into account the outward normal to the surface and the angle it makes with the direction of electric field ( or electric field lines). This helps us understand the quantity of field lines passing through the surface or if any passes through it at all. (If you have studies about electric flux, you must know that area is considered a vector quantity here)
@@DushyanthEdadasula but while choosing cylinder during integration of da we put A ( which is the area of flat surface of cylinder on both sides i.e: circle ) but when we choose cuboid the area of flat surfaces become the area of square ... Please clear me anyone
Can someone clear this doubt of mine that if we're talking about charge enclosed by the gaussian surface why dont we take it as (2×sigma×a) as we've two sides of sheet ?

Same!
I don't like Alakh sir lol... he's creepy.
plus alakh sir's videos are rlly long, these are short and concise but both of teach really well
Alakh sir videos are great ..and takes patience to understand . But here the videos are visually explained , so you can feel the physics into depth .

as an American physics student, it's a beautiful video!
hey, I always wanted to know is the level of maths and physics taught in American High schools and Indian High schools same ?

After going through several videos finally found what I was looking for,simply amazing 👏
Thank apot sir!
You are AMAZING SIR....
Student from Haryana......
Sir salam cordially to your concept about physics..
extremely well explained, WOW . Its good that the pace is a bit slow for such important concepts
Just to the point and easy explanation... Much appreciated 👍
Sir your English is awesome to understand every person
you are simply amazing
Wonderous Video❤️
1:48 - selection criterion for surface
2:11 - 3 spl cases
I'm soo grateful that I found this channel :) .Your explanations are superb . All my doubts would be cleared at the end of the video.
Great Explanation, Fantastic teacher!!
this kind of video makes me feel to drop uni and get a degree-level knowledge on my own from utube videos
Thanks a lot Sir. Please keep producing such videos.

Fantastic😍
but what is the proof that in this case we can use gauss law. is there any mathematical proof or just memorization?
somone give that man some top he deserve it
I tried on my own and I use cube instead and got the same answer!
@ 7:10
SIR, CAN WE USE A RECTANGULAR CUBOID, AS IT TOO IS FLAT, AND CAN ENCLOSE THE ENTIRE SHEET? IN OUR TEXTBOOKS IT's GIVEN LIKE THAT
Good question
Yes we can , there will be six surfaces and on two surfaces only the angle between ds and e will not be 90 degree but zero . So yes we can use.
Very counter intuitive that the distance doesn't matter.
I am the first viewer of your video 7:28pm
I'm at 8:56 pm
Sir you are great 😃
Loved this
Very best sir
Sir why can't you add the related videos (infinite charged wire and sphere)in the description.
simply beautiful
Wow! ❤️❤️❤️❤️❤️
thnks sir
Sir make gaseous state lectures
If it is infinite cube, maybe in 4th dimension it would be directly proportional to the r.
Mind blowing 💀
May be a silly question but I still don't fully understand why it's 2EA, aren't the two Es acting in opposite directions?
Electric field doesn't cancel out on being opposite . It's not force , it's the intensity of force acting on unit charge
we can't we take a cube as gaussian surface?
It would be the same result as taking cylinder . The area on the left side of Gauss eqn will cancel out the area on right side of the eqn
Please come in front of us in the end and starting of video
Sir why the area always show outward direction???
To calculate flux through a surface, we have to take into account the outward normal to the surface and the angle it makes with the direction of electric field ( or electric field lines). This helps us understand the quantity of field lines passing through the surface or if any passes through it at all. (If you have studies about electric flux, you must know that area is considered a vector quantity here)
I am afraid...any number, howsoever big is alwar closer to zero than to infinity....
Ok, but why are you afraid lol
Sir do all the lectures with your language only sir
Why didn't we used a rectangle why only cylinder. I mean rectangle also have flat ends?
Sir,why can't we choose ah cuboid which has flat surface at the both side of the plate and passes through the sheet.
One can choose any shape. The answer remains the same because the flux doesn't pass through the walls.
@@DushyanthEdadasula but while choosing cylinder during integration of da we put A ( which is the area of flat surface of cylinder on both sides i.e: circle ) but when we choose cuboid the area of flat surfaces become the area of square ... Please clear me anyone
@@manojmaheshwari4055 you're on the right track.
In fact you can choose a tube with any kind of cross section. The 'A' on both sides will cancel anyway, leaving you with the same answer.
@@DushyanthEdadasula ya ur right bro ... Tq bro 🙏🏻
sir can we use a cuboid instead of a cylinder and put it the same was as the cylinder
yes....any shape, it doesn't matter because in the end area cancels outs
Can someone clear this doubt of mine that if we're talking about charge enclosed by the gaussian surface why dont we take it as (2×sigma×a) as we've two sides of sheet ?
It's a thin sheet so the charges reside on the plane
@@AbhiramGSrivathsaso charges reside on one side only?
@@avishasrivastavaxi-e7255 the charges are embedded in the thin sheet. it's very thin so one single charge is visible on both the sides of the sheet
Sir why not use a cube?
Sir is this sheet a conductor or insulator?
Doesn't matter as long as the charge is static
