The ratio of binding energy of a satel...

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

A

`(2(R+h))/(R)`

B

`(R+h)/(2R)`

C

`(R+h)/(R)`

D

`(R)/(R+h)`

Text Solution

Verified by Experts

The correct Answer is:
A
Binding energy on the surface on the earth, `E_(1)=("GMm")/(R)`
Binding energy of revolving satellite, `E_(2)=("GMm")/(2(R+h))`
`therefore (E_(1))/(E_(2))=(2(R+h))/(R)`
