    The dimensions of power are                           [CPMT 1974, 75; SCRA 1989]

    A)             \[{{M}^{1}}{{L}^{2}}{{T}^{-3}}\]

    B)             \[{{M}^{2}}{{L}^{1}}{{T}^{-2}}\]

    C)             \[{{M}^{1}}{{L}^{2}}{{T}^{-1}}\]

    D)               \[{{M}^{1}}{{L}^{1}}{{T}^{-2}}\]

    Correct Answer: A

    Solution :

                     Power = \[\frac{\text{Work done}}{\text{Time}}=\left[ \frac{M{{L}^{2}}{{T}^{-2}}}{T} \right]=[M{{L}^{2}}{{T}^{-3}}]\]
