    The dimensional formula for impulse is [EAMCET 1981; CBSE PMT 1991; CPMT 1978; AFMC 1998; BCECE 2003]

    A)             \[ML{{T}^{-2}}\]    

    B)             \[ML{{T}^{-1}}\]

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

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

    Correct Answer: B

    Solution :

                     Impulse = Force \[\times \] Time = \[[ML{{T}^{-2}}]\,[T]=[ML{{T}^{-1}}]\]
