Gravitation Question 189

Question: A satellite of mass m is circulating around the earth with constant angular velocity. If radius of the orbit is [R0] and mass of the earth M, the angular momentum about the centre of the earth is [MP PMT 1996; RPMT 2000]

Options:

A) [mGMR0]

B) [MGmR0]

C) [mGMR0]

D) [MGMR0]

Show Answer

Answer:

Correct Answer: A

Solution:

Angular momentum = Mass ×Orbital velocity ×Radius [=m×(GMR0)×R0=mGMR0]
