A satellite of mass 'm' is revolving around the earth of mass 'M' in an orbit of radius 'r' with constant angular velocity ' ^ . The angular momentum of the satellite is (G = gravitational constant)
Options
- Am ( GMr )
- Bm ( GMr )^ 1 / 2
- C( GMmr )^ 1 / 2
- D( GMr m )²
Correct answer
B. m ( GMr )^ 1 / 2
Step-by-step solution
(B) aligned Angular momentum &=m v r=m G M r r &=m G M r &=m(G M r)^ 1 2 aligned
