A satellite moves around the earth in a circular orbit with speed `v`. If `m` is the mass of the satellite, its total energy is

A

`1/2 mv^(2)`

B

`-1/2 mv^(2)`

C

`3/2 mv^(2)`

D

`1/2 (PE)`

Text Solution

Verified by Experts

The correct Answer is:
D
Total energy ` = (-1)/2 (GMm)/r`
` PE = (GMm)/r`
Total energy is ` 1/2 ` of PE .
