The ratio of the binding energy of a satellite at rest on earth's surface to the binding energy of a satellite of same mass revolving around the earth at a height $h$ above the earth's surface is $(R$ = radius of the earth $)$ .

Options:

Answer:

Solution:

Binding energy on the surface of the earth

$E_{1} = \frac{G M m}{2 R}$

Binding energy of revolving satellite

$E_{2} = \frac{G M m}{2 (R + h)}$

$∴ \frac{E_{1}}{E_{2}} = \frac{(R + h)}{R}$
