Vedclass · Answer

(D) For a spherical shell,the electric potential $V$ inside is constant and equal to the potential at the surface. If the shell is placed in an external electric field,charges are induced on the surface of the shell. These induced charges create an electric field inside the shell that exactly cancels the external electric field,resulting in a net electric field of zero inside the conductor (electrostatic shielding). However,the induced charges themselves contribute to the electric potential inside the shell. The potential due to induced charges at any point inside the shell is not necessarily zero; it is such that it keeps the total potential inside constant. Therefore,statement $C$ is incorrect. Statement $A$ is incorrect because a shell can have a non-zero potential while being neutral if placed in an external field. Statement $B$ is incorrect because the electric field inside a conducting shell is zero due to electrostatic equilibrium,regardless of whether the charge distribution is uniform or non-uniform. Thus,the correct answer is $D$.
