If the Earth is treated as a sphere of radius R and mass M, its angular momentum about the axis of rotation with the time period T is:
- \(\frac{\pi \mathrm{MR}^{3}}{\mathrm{~T}}\)
- \(\frac{\mathrm{MR}^{2} \mathrm{~T}}{2 \pi}\)
- \(\frac{2 \pi \mathrm{MR}^{2}}{\mathrm{~T}}\)
- \(\frac{4 \pi M R^{2}}{5 T}\)
Answer
(D) 4 M R^ 2 5 T
