Question

Derive an expression for the critical velocity?

Answer 1

The satellite is moving with velocity Vc and the radius of the circular orbit is r = R + h. This is the expression for critical velocity of a satellite moving in a circular orbit around the Earth. where gh is the acceleration due to gravity at a height h above the surface of the Earth.
