NEET Physics Gravitational Potential Energy MCQ Question
A satellite of mass m is moving in a circular orbit of radius a around a planet of mass M (M >> m). What is the gravitational potential energy of the satellite in this orbit?
-(G * M * m) / a
G * M * m / a
-(2 * G * M * m) / a
2 * G * M * m / a
Correct Answer
Detailed Explanation
The gravitational potential energy of a satellite in a circular orbit is given by V = -(G * M * m) / a, as derived from the potential energy expression where r = a.
