Question

drive an expression for critical velocity of satellite ​

Answer 1

Answer:

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.

Explanation:

Consider a satellite of mass m revolving round the Earth at a, height 'h' above the surface of the Earth.

Let M be the mass and R be the radius of the Earth.

The satellite is moving with velocity V and the radius of the circular orbit is.
