Correct answer
C
Step-by-step explanation
Gravitational potential energy on the earth surface of a body
U =
And at the height h from the earth surface the potential energy
= [ as h = R ]
So the gain in the potential energy
Now
U =
And at the height h from the earth surface the potential energy
= [ as h = R ]
So the gain in the potential energy
Now
