    Force F on a particle moving in a straight line varies with distance d as shown in the figure. The work done on the particle during its displacement of 12 m is

    A)  21 J         

    B)  26 J

    C)  13 J         

    D)  18 J

    Correct Answer: C

    Solution :

     Work done = Area under \[(F-x)\]graph \[=2\times (7-3)+\frac{1}{2}\times 2\times (12-7)\] \[=8+\frac{1}{2}\times 10=8+5=13\,J\]
