Physics Question on momentum

The dimension of angular momentum is

A

M0L1T−1M^{0}L^{1}T^{-1}

B

M1L2T−2M^{1}L^{2}T^{-2}

C

M1L2T1M^{1}L^{2}T^{1}

D

M2L1T−2M^{2}L^{1}T^{-2}

Answer

M1L2T1M^{1}L^{2}T^{1}

Explanation

Solution

Dimension of angular momentum
L=r×pL = r \times p
=[L][MLT−1]=[ML2T−1]=[ L ]\left[ MLT ^{-1}\right]=\left[ ML ^{2} T ^{-1}\right]
