NEET Physics Gravitational Potential Energy MCQ Question
What is the total mechanical energy of a mass m moving in a circular orbit of radius a around a much larger mass M?
-G * M * m / (2 * a)
G * M * m / (2 * a)
-G * M * m / a
G * M * m / a
Correct Answer
Detailed Explanation
The total mechanical energy for a mass m in a circular orbit around a much larger mass M is given by E = -G * M * m / (2 * a), as per the formula for potential and kinetic energies in such systems.
