    The solar constant is defined as the energy incident per unit area per second. The dimensional formula for solar constant is

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

    B)    \[[ML{{T}^{-2}}]\]

    C)  \[[M{{L}^{2}}{{T}^{-2}}]\]

    D)  \[[M{{L}^{0}}{{T}^{-3}}]\]

    Correct Answer: D

    Solution :

    [d] Energy incident per unit area per second \[=\frac{Energy}{area\times \sec ond}=\frac{M{{L}^{2}}{{T}^{-2}}}{{{L}^{2}}T}=M{{T}^{-3}}\]
