NEET Physics Gravitational Potential Energy MCQ Question
A satellite of mass m is in a circular orbit of radius a around a planet of mass M. The gravitational potential energy of the satellite is given by which of the following equations?
-(G * M * m) / a
(G * M * m) / (2 * a)
-(2 * G * M * m) / a
(G * M * m) / a
Correct Answer
Detailed Explanation
The gravitational potential energy V is given by V = -G * M * m / a for a satellite in a circular orbit, as per the context where potential energy is defined in terms of mass, gravitational constant, and orbit radius.
