Suppose we have a sphere with a uniform surface charge. According to Gauss law the electric field inside such a sphere is zero. So if I put a charge ( let me call it Q from here) in it, it wouldn't experience any force, would it?
What I don't understand is this: the charge Q we actually put inside does create an electric field so our sphere should move thus it only comes down to picking the right point of reference so one could say that it is our charge Q which is actually moving
However, if the sphere can't move and I put my charge not in the center of the sphere it would feel a stronger attraction to the closest point than to any other thus should move and if it moves there is an electric field inside.
Thus according to my logic in both cases the charge inside is affected
Please help me out, I am really struggling on this one
