A satellite of mass m is in a stable circular orbit around the earth at an altitude of about 100 kilometres. If M is the mass of the earth, R is its radius and g the acceleration due to gravity, the time period T of the revolution of the satellite is given by
- \(T=2 \pi \sqrt{\frac{R}{g}}\)
- \(T=2 \pi \sqrt{\frac{g}{R}}\)
- \(T=2 \pi \sqrt{\frac{M R}{m g}}\)
- \(T=2 \pi \sqrt{\frac{m R}{M g}}\)
Answer
(A) T=2 R g
