A satellite of mass m is placed at a distance r from the centre of earth (mass M ). The mechanical energy of the satellite is

A

`-(GMm)/(r)`

B

`(GMm)/(r)`

C

`(GMm)/(2r)`

D

`-(GMm)/(2r)`

Text Solution

Verified by Experts

The correct Answer is:
D
If a satellite of mass m is placed at a distance r form the centre of the earth (of mass M), the mechanical energy of the satellite is given by `(-GMm)/(2r)`.
