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
- A2 ( R + h ) R
- BR + h 2 R
- CR + h R
- DR R + h
Correct answer
C. R + h R
Step-by-step solution
Binding energy on the surface of the earth E 1 = G M m 2 R Binding energy of revolving satellite E 2 = G M m 2 ( R + h ) ∴ E 1 E 2 = ( R + h ) R
