The dimensional formula of angular impulse is:
A$\left[\mathrm{M} \mathrm{L}^2 \mathrm{~T}^1\right]$
B$\left[\mathrm{M} \mathrm{L}^2 \mathrm{~T}^2\right]$
C$\left[\mathrm{ML} \mathrm{T}{ }^{-1}\right]$
D$\left[\mathrm{M} \mathrm{L}^2 \mathrm{~T}^{-1}\right]$
(JEE MAIN-2024)
Solution
Angular impulse $=$ change in angular momentum.
[Angular impulse $]=[$ Angular momentum $]=[\mathrm{mvr}]$
$=\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]$
[Angular impulse $]=[$ Angular momentum $]=[\mathrm{mvr}]$
$=\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]$
