    Dimensional formula of stress is

    A)             \[{{M}^{0}}L{{T}^{-2}}\]          

    B)             \[{{M}^{0}}{{L}^{-1}}{{T}^{-2}}\]

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

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

    Correct Answer: C

    Solution :

                    Stress = \[\frac{\text{Force}}{\text{Area}}=\frac{[ML{{T}^{-2}}]}{[{{L}^{2}}]}=[M{{L}^{-1}}{{T}^{-2}}]\]
