Consider a charge q, inside a cavity of a spherical conductor. Let's explore how the induced charges get redistributed in electrostatic conditions.

The charge distribution on the outer surface doesn't depend on the charge distribution on inner surface so outer charge distribution must be uniform

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

@badpineapple9120 Ай бұрын

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

@abhirupkundu2778 Ай бұрын

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

@albertomontecarlo6231 Жыл бұрын

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..

So what is the field inside the cavity?

@samramzi4639 3 ай бұрын

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?

@tarandeepsinghkhurana2874 2 жыл бұрын

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 ?

@navkhr352 2 ай бұрын

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

@plonksmag2686 Жыл бұрын

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??
