Question

If the Earth is treated as a sphere of radius R and mass M, its angular momentum about the axis of rotation with period T is?

Answer 1

Hey Dear,

◆ Answer -

L = 4/5 πMR²/T

◆ Explaination -

Moment of inertia of solid sphere is given by -

I = 2/5 MR²

Angular velocity of the earth is given as -

ω = 2π/T

Angular momentum about axis of rotation is given by -

L = I × ω

L = 2/5 MR² × 2π/T

L = 4/5 πMR²/T

Thus, angular momentum of earth about its axis of rotation is 4/5 πMR²/T .
