    If h is height and g is acceleration due to gravity, then the dimensional formula of \[\sqrt{\frac{2h}{g}}\] is the same as that of -

    A) time                             

    B) mass

    C) volume             

    D) velocity

    Correct Answer: A

    Solution :

    \[\left[ \sqrt{\frac{2h}{g}} \right]\,\,=\,\,\sqrt{\frac{{{M}^{0}}{{L}^{1}}{{T}^{0}}}{{{M}^{0}}{{L}^{1}}{{T}^{-2}}}}\,\,=\,\,\sqrt{{{M}^{0}}{{L}^{1}}{{T}^{2}}}\,\,\left[ {{T}^{1}} \right]\,\,=\,\,Time\]
