Question

expression for 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.....

Answer 2

Explanation:

a. Let,

M = mass of the earth

R = radius of the earth

h = height of the satellite from the earth’s surface

m = mass of the satellite

vc = critical velocity of the satellite in the given orbit
