STANDARD Physics Energy of Satellite MCQ Question
For a satellite moving in an orbit around the Earth, the ratio of its potential energy to kinetic energy is
1
−1
2
−2
Correct Answer
Detailed Explanation
The kinetic energy of a satellite in orbit is K = GMm/2r and the potential energy is U = -GMm/r. The ratio U/K = -2, indicating that the potential energy is twice the kinetic energy but negative.
