Suppose I put an (uncharged) hollow conducting sphere with inner radius a and outer radius b in an external electric field in the positive z direction.
Apparently, the potential INSIDE the sphere -- that is, for 0 < r < a -- is zero. Can someone explain why this is? I understand that the conductor is an equipotential, so we can set the potential for a < r < b to zero. But does this have any bearing on whether the potential is zero for 0 < r < a?
