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

    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..

    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?

    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.
