Conductor with charge inside a cavity | Electrostatic potential & capacitance | Khan Academy
Consider a charge q, inside a cavity of a spherical conductor. Let's explore how the induced charges get redistributed in electrostatic conditions.

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

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

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
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
The charge distribution on the outer surface doesn't depend on the charge distribution on inner surface so outer charge distribution must be uniform
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.
Physics always leaves me speechless 💯
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
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
This result is remarkable. I remember seeing this in Physics class but as usual throwing out all the amazement.
Why I didn't know this channel before?? The video is so clear and easy to understand!!! Thank you very much
Wow extremely clear explanation. The only video i found that covers this topic in depth.
great video! We need more educators like you
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!!
I fell in love with your video every time
you're a lifesaver thank you
Outstanding amazing mind blowing sir
Thanks it helped a lot
Thanks a lot
THANK YOU!
LOVE FROM UGANDA KI KALIGHATI 😌🔥
thanks a lot
Nice explanation
Your explanation is very helpful...thankyou so much🤗
Really got a charge out of the lecture, you have great energy.
You are one of the greatest teacher
Best explanation
Superb
Mahn ur just too gud pls continue this good work
Thanks
I am so much confused about this topic but thank u so much for solving my doubt🤩
Thank you 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.
Thankyou
Amazing video! Thanks from Portugal

Also positive charges are immobile in a solid conductor
What if the sphere is grounded, would it have the same results? Please answer as soon as possible, Ty
Thnku sooo much sir nd hatts of to your commendable teachingg
thnks sir
Thankyouu
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..
hush finally my doubt is solved
Hi, does that means I have a field equal to the resonance field outside of the room (faraday cage) but more scattered ?
will there be any charge induced on the outer surface of the cavity?
Sir will you cover capacitor and capacitance also.?
So what is the field inside the cavity?
Simply awesome. Please create more such videos on difficult concepts.
In case of neutral dielectric sphere wht happen??
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?
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
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
Is the charge on outer surface same as in centre or Different?
@navkhr352

It has to be same
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??
How'd he get the cursor to have two fingers pointed out :0
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
