Consider the two identical particles shown in the given figure. They are released from rest and may move towards each other under the influence of mutual gravitational force. The gravitational potential energy of the two particle system
A
zero
B
constant 
C
decreases as the separation decreases
D
increases as the separation decreases
Text Solution
Verified by ExpertsThe correct answer is:
C
When particles are released from rest their separation decreases. Therefore, gravitational
potential energy of the system decreases.
