Dimensional formula of angular momentum is

Dimensional formula of angular momentum is

Options

  1. A[ML2 T−1]\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]
  2. B[M2 L2 T−2]\left[\mathrm{M}^2 \mathrm{~L}^2 \mathrm{~T}^{-2}\right]
  3. C[ML2 T−3]\left[\mathrm{ML}^2 \mathrm{~T}^{-3}\right]
  4. D[MLT−1]\left[\mathrm{MLT}^{-1}\right]

Correct answer

A. [ML2 T−1]\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]

Step-by-step solution

 Angular momentum = moment of inertia × angular velocity \begin{aligned} \text{ Angular momentum }= & \text{ moment of inertia } \\ & \times \text{ angular velocity }\end{aligned} =\left[\mathrm{ML}^2\right] \times\left[\mathrm{T}^{-1}\right]=\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]
