  • question_answer
    A hollow metal sphere of radius 10 cm is charged such that the potential on its surface becomes 80 V. The potential at the centre of the sphere is:

    A) 80 V

    B) 800 V

    C) 8 V

    D) zero            

    Correct Answer: A

    Solution :

    (a) 80V The potential at the centre of the sphere is 80 V, because it remains same at each point under the metallic hollow sphere.
