    Which of the following quantities does not depend on the choice of zero potential or zero potential energy?
    (a) Potential at a point
    (b) Potential difference between two points
    (c) Potential energy of a two-charge system
    (d) Change in potential energy of a two-charge system
    digAnsr:   b,d
    Ans : (b) Potential difference between two points
    (d) Change in potential energy of a two-charge system
    Potential and potential energy depend on the choice of a reference point of zero potential or zero potential energy. But the difference of potential and energy does not depend on the choice of the reference point. Hence, the correct options are
    (b) and
    (d).
