- B \(\left[\mathrm{M}^{1} \mathrm{L}^{2} \mathrm{T}^{-2}\right]\)
- C \(\left[\mathrm{M}^{1} \mathrm{L}^{2} \mathrm{T}^{1}\right]\)
- D \(\left[\mathrm{M}^{2} \mathrm{L}^{1} \mathrm{T}^{-2}\right]\)
Answer & Solution
Correct Answer
(C) \(\left[\mathrm{M}^{1} \mathrm{L}^{2} \mathrm{T}^{1}\right]\)
Step-by-step Solution
Detailed explanation
Dimension of angular momentum \(\mathbf{L}=\mathbf{r} \times \mathbf{p}\) \(=[\mathrm{L}]\left[\mathrm{MLT}^{-1}\right]=\left[\mathrm{ML}^{2} \mathrm{T}^{-1}\right]\)
