STANDARD Physics Energy of Satellite MCQ Question
Type: MCQ-conceptual-Medium-Class 11
For a satellite moving in an orbit around the Earth, the ratio of its potential energy to kinetic energy is
A
1
B
−1
C
2
D
−2
Correct Answer
Option D
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.
