(D) hollow conducting sphere is an equipotential volume. Since the entire material of the conductor is at the same potential,the potential at any point on the surface ($A$ and $B$) and any point inside the cavity $(C)$ must be equal. Therefore,$V_A = V_B = V_C$.

$A$ hollow conducting sphere is placed in an electric field produced by a point charge placed at $P$ as shown in the figure. Let $V_A, V_B$,and $V_C$ be the potentials at points $A, B$,and $C$ respectively,where $A$ and $B$ are on the surface of the sphere and $C$ is inside the sphere. Then:

A
$V_C > V_B$
B
$V_B > V_C$
C
$V_A > V_B$
D
$V_A = V_B = V_C$
