Question

Define the binding energy of a satellite obtain an expression for binding energy of a satellite revolving around the Earth at certain attitude​

Answer 1

Answer:

BINDING ENERGY = The minimum amount of energy required for satellite to escape from earth's gravitational influence is called as Binding Energy of satellite.

EXPRESSION-

Consider a satellite of mass m revolving around the earth in a circular orbit ar a height h above the surface of earth.

M = Mass of Earth

R = Radius of Earth

Vc = Critical Velocity of Satellite

r = R+h = Radius of Orbit

The Critical Velocity of Satellite is Given by

Vc =

$\sqrt{ gm \div r}$

therefore Be is

$1gmm \div 2r$
