The long range force experienced by a neutral particle with a finite mass

The long range force experienced by a neutral particle with a finite mass is gravitational force. In this universe each body attracts other body with a force that is directly proportional to the product of their masses $\left(m_1\right.$ and $\left.m_2\right)$ and inversely proportional to the square of distance $(r)$ between them. $F=\frac{G m_1 m_2}{r^2}$ This force is called gravitational force.
