    The unit of potential energy is                                                     [AFMC 1991]

    A)       \[g(cm/{{\sec }^{2}})\]                               

    B)       \[g{{(cm/\sec )}^{2}}\]

    C)       \[g(c{{m}^{2}}/\sec )\]                               

    D)      \[g(cm/\sec )\]

    Correct Answer: B

    Solution :

                            Potential energy \[=mgh=g\left( \frac{cm}{{{\sec }^{2}}} \right)cm=g{{\left( \frac{cm}{\sec } \right)}^{2}}\]
