  • question_answer
    In the electric field of a point charge \[q\], a certain charge is carried from point \[A\] to \[B\], \[C\], \[D\] and \[E\]. Then the work done                                                                                                                                       [NCERT 1980]

    A)                    Is least along the path \[AB\]

    B)                    Is least along the path \[AD\]

    C)                    Is zero along all the paths \[AB,\ AC,\ AD\] and \[AE\]

    D)                    Is least along \[AE\]

    Correct Answer: C

    Solution :

                 ABCDE is an equipotential surface, on equipotential surface no work is done in shifting a charge from one place to another.
