Physics - Unit & Dimension Question with Solution | TestHub

As we know that, Impulse, $I=$ force $(F)\times$ small time interval $\begin{array}{ll}I=ma\times t& [\because F=ma]\\ I=[\mathrm{M}]\left[{\mathrm{LT}}^{-2}\right]\times [\mathrm{T}]& \\ I=\left[{\mathrm{MLT}}^{-1}\right]& \end{array}$ Hence, the correct dimensional formula for impulse is given by $[\mathrm{ML}{\mathrm{T}}^{-1}1.$
