If the earth is treated as a sphere of radius R and mass M; its angular momentum about axis of rotation with period T is
View answer and explanation
Correct option: D
4πMR25T\frac{{4\pi M{R^2}}}{{5T}}
Option D (4πMR25T\frac{{4\pi M{R^2}}}{{5T}}) is correct because it correctly calculates the angular momentum of a sphere using the formula J=IωJ = I\omega with the correct moment of inertia and angular velocity.
