(B) For a hollow conducting sphere (or a charged spherical shell),the electric field inside the sphere is zero $(E = 0)$.Since the electric field is the negative gradient of the potential $(E = -dV/dr)$,if $E = 0$,then the potential $V$ must be constant throughout the interior of the sphere.Therefore,the potential at any point inside the sphere,including the center,is equal to the potential at its surface.Given that the potential at the surface is $10 \ V$,the potential at the center is also $10 \ V$.

The electric potential on the surface of a hollow sphere of radius $5 \ cm$ is $10 \ V$. What is the electric potential at its center?
