Q. If the gravitational potential energy of two point masses infinitely away is taken to be zero then gravitational potential energy of a galaxy is

Gravitation

Solution:

A galaxy is a bounded system, for a bounded system or closed system like planet-sun, satellite Earth, electron- nucleus etc. total energy and the potential energy both are negative.
