Q. The dimensional formula for impulse is
A) $\left\lbrack {MLT}^{- 1} \right\rbrack$
B) $\left\lbrack {ML}^{- 1}T \right\rbrack$
C) $\left\lbrack M^{- 1}{LT}^{- 1} \right\rbrack$
D) $\left\lbrack {ML}^{- 1}T^{- 1} \right\rbrack$
Explanation
$Impulse = force\ \times time$ $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = \left\lbrack MLT^{- 2} \right\rbrack\lbrack T\rbrack$ $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = \left\lbrack MLT^{- 1} \right\rbrack$
