    Dimensions of stress are:              [NEET 2020]

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

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

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

    D) \[[ML{{T}^{2}}]\]

    Correct Answer: C

    Solution :

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