Question

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

• A. Gravitational force
• B. Weak force
• C. Electromagnetic force
• D. Strong force

Answer 1

Answer: (A)

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 $(m_1$ and $m_2$ ) 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.
