The dimensional formula of angular impulse is :

The dimensional formula of angular impulse is :

Options

A $[ M{L}^{– 2}{T}^{– 1} ]$
B $[ M{L}^{2}T{}^{– 2} ]$
C $[ MLT{}^{– 1} ]$
D $[ M{L}^{2}T{}^{– 1} ]$

Correct answer

D. $[ M{L}^{2}T{}^{– 1} ]$

Step-by-step solution

Angular impulse = change in angular momentum.

[Angular impulse] = [Angular momentum] $= [ mvr ]$

$= [ M{L}^{2}T{}^{– 1} ]$
