  • question_answer
    Two spheres each of mass M are situated at a distance 2d (see figure). A particle of mass \[m(m<<M)\]is taken along the path shown in figure. The work done in the process from A to B is

    A) \[\frac{7GMm}{d}\]

    B) \[\frac{8GMm}{d}\]

    C) \[-\frac{8GMm}{d}\]

    D) zero

    Correct Answer: D

    Solution :

    [d] \[{{W}_{AB}}=m\left( {{V}_{_{B}}}-{{V}_{A}} \right);\,But\,\,{{V}_{A}}={{V}_{B}}and\,\,so\,{{W}_{AB}}=0\]
