    A hollow conducting sphere is placed in an electric field produced by a point charge placed at P as shown in figure, Let \[{{V}_{A}}{{V}_{B,}}{{V}_{C}}\]potentials at points A, B and C respectively.         Then

    A) \[{{V}_{C}}>{{V}_{B}}\]                                

    B) \[{{V}_{B}}>{{V}_{C}}\]

    C) \[{{V}_{A}}>{{V}_{B}}\]                                

    D) \[{{V}_{A}}={{V}_{C}}\]

    Correct Answer: D

    Solution :

    At each point on the surface of a conducting sphere the potential is equal. So,          \[{{V}_{A}}={{V}_{B}}={{V}_{C}}\]
