Question: The dimensional formula for impulse is...

The dimensional formula for impulse is

A

MLT−2MLT^{- 2}

B

MLT−1MLT^{- 1}

C

ML2T−1ML^{2}T^{- 1}

D

M2LT−1M^{2}LT^{- 1}

Answer

MLT−1MLT^{- 1}

Explanation

Solution

Impulse = Force ×\times Time = [MLT−2][T]=[MLT−1]\lbrack MLT^{- 2}\rbrack\lbrack T\rbrack = \lbrack MLT^{- 1}\rbrack
