What is the formula for Critical Velocity of Satellite Orbiting at a height from the Earth’s Surface?
Posted in Gravitation | Email This Post |Critical velocity is the minimum velocity of projection for which satellite revolves in a circular orbit around the earth.
G = Universal Gravitational Constant
gh = acceleration due to gravity at height h above earth’s surface
M= Mass of the earth
R =Radius of the earth
h = height at which satellite is orbiting
If satellite is revolving very close to the earth’s surface, then
So Vc= √ gh(R+h) is the formula for Critical Velocity of Satellite Orbiting at height h from the Earth’s Surface
