    The dimensional formula for impulse is

    A)  \[[ML{{T}^{-1}}]\]                          

    B)  \[[M{{L}^{-1}}T]\]

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

    D)  \[[M{{L}^{-1}}{{T}^{-1}}]\]

    Correct Answer: A

    Solution :

    Impulse = force \[\times \] time                 \[=[ML{{T}^{-2}}]\,[T]\]                 \[=[ML{{T}^{-1}}]\]
