    Dimensions of kinetic energy are                                               [Bihar PET 1983; DPET 1993; AFMC 1991]

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

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

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

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

    Correct Answer: A

    Solution :

                    Kinetic energy = \[\frac{1}{2}m{{v}^{2}}=M{{[L{{T}^{-1}}]}^{2}}=[M{{L}^{2}}{{T}^{-2}}]\]
