Question

The dimensional formula of angular momentum is

• A. $[M{L}^2{T}^{-2}]$
• B. $[M{L}^{-2}{T}^{-1}]$
• C. $[ML{T}^{-1}]$
• D. $[M{L}^2{T}^{-1}]$

Answer 1

Answer: (D)

Angular momentum $L$
$=$ Moment of inertia $I\times$ Angular velocity $\omega$.
$\therefore$ Dimensional formula $L=\left[M{L}^2\right]\left[T^{-1}\right]$
$=\left[M{L}^2{T}^{-1}\right]$
