    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 12m is:

    A) 21J                  

    B) 26J     

    C) 13J                  

    D) 18J

    Correct Answer: C

    Solution :

    Work done = Area under F-x graph \[=2\times \left( 7-3 \right)+\frac{1}{2}\times 2\times \left( 12-7 \right)\] \[=2\times 4+5 =13 Joule\]
