    The potential energy of a particle varies with distance\[x\]as shown in the graph the force acting on the particle is zero at

    A)  C                               

    B)  B                    

    C)  B and C         

    D)    A and D

    Correct Answer: C

    Solution :

    \[F=-\frac{dU}{dx}\]It is clear the slope of \[U-x\]curve is zero at point B and C Therefore, \[F=0\]for point B and C. Hence, the correction option is (c).
