potential energy two masses

Question

Potential energy of two masses m and m separated by r is:

RankGuru · Accepted Answer

The gravitational potential energy of a pair of masses is defined by:
$U = -\frac{G m_1 m_2}{r}$
- 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.
