Question

The dimensional formula of angular impulse is :

• A. [M L^–2 T^–1]
• B. [M L² T^–2]
• C. [M L T^–1]
• D. [M L² T^-1]

Answer 1

The Correct Option is D

Angular impulse is defined as the change in angular momentum:

$$\text{Angular impulse} = [\text{Angular momentum}] = [mvr] = [ML^2T^{-1}]$$

Thus, the correct dimensional formula is $[ML^2T^{-1}]$.
