The total energy of a revolving satellite around the earth is `-KJ`. The minimum energy required to throw it out of earth's gravitational fields is

A

`KJ`

B

`(K)/(2)J`

C

2KJ

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
If the satellite could be through out side the earth’s gravitational field, its minimum total energy =0.
So, `-K+K.=0`
K.=KJ
