Q. The dimensional formula for impulse is same as the dimensional formula for
A) Momentum
B) Force
C) Rate of change of momentum
D) Torque
Explanation
Momentum = $mv = \lbrack ML^{\ }T^{- 1}\rbrack$ Impulse = Force$\ \times$ Time = [$MLT^{- 2}\rbrack \times \lbrack T\rbrack = \lbrack MLT^{- 1}\rbrack$
