MCQ
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
    $\left[\mathrm{ML} \mathrm{T}{ }^{-1}\right]$
  • ✓
    $\left[\mathrm{M} \mathrm{L}^2 \mathrm{~T}^{-1}\right]$
✓

Answer

Correct option: D.
$\left[\mathrm{M} \mathrm{L}^2 \mathrm{~T}^{-1}\right]$
d
Angular impulse $=$ change in angular momentum.

[Angular impulse $]=[$ Angular momentum $]=[\mathrm{mvr}]$

$=\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]$
