An artificial satellite moving in a circ...

An artificial satellite moving in a circular orbit around the Earth has a total (kinetic + potential) energy `E_(0)`. Its potential energy is:

A

`1.5E_(0)`

B

`E_(0)`

C

`2E_(0)`

D

`-E_(0)`

Text Solution

Verified by Experts

The correct Answer is:
C
Total energy = `(GMm)/(2r)=E_(0)`
Potential energy = `-(GMm)/(r)=2E_(0)`
