For a satellite moving in a circular orbit around the earth, the ratio of its potential energy to kinetic energy is

A

`1`

B

`-1`

C

`2`

D

`-2`

Text Solution

Verified by Experts

The correct Answer is:
D
Kinetic energy of the satellite, `K=(GM_(E)m)/(2r)`
Potential energy of the satellite, `U=-(GM_(E)m)/r`
Their corresponding ratio is `U/K=-2`
