Solution
Correct Answer:
-GMm/r
The gravitational potential energy of a pair of masses is defined by: U=−rGm1m2
- The negative sign signifies that the system is bound, which is characteristic of attractive forces.
- Work must be done by an external agent to separate the masses.
This easy difficulty physics question is from the chapter gravitation, covering the topic of potential energy two masses. It appeared in the 2025 exam.
