    Electric potential at the centre of a charged hollow metal sphere is

    A)  zero

    B)  twice as that on the surface

    C)  half of that on the surface

    D)  same as that on the surface

    Correct Answer: D

    Solution :

                     Electric potential of charged spherical shell \[V=\frac{q}{4\pi {{\varepsilon }_{0}}R}\]                             \[(0\le r\le R)\] \[\therefore \]Electric potential at centre = Electric potential on the surface.
