  • question_answer
    A hollow metal sphere of radius 5 cm is charged so that the potential on its surface is 10 V.  The potential at the centre of the sphere is                                   [IIT 1983; MNR 1990; MP PET/PMT 2000; DPMT 2004]

    A)                    0 V

    B)                                      10 V

    C)                    Same as at point 5 cm away from the surface

    D)                    Same as at point 25 cm away from the surface

    Correct Answer: B

    Solution :

                 Since potential inside the hollow sphere is same as that on the surface.
