Question

Why is gravity the weakest force?

Answer 1

The reason for gravity being the weakest force:

• Mathematically gravitational force is given as,

$F=\frac{GMm}{R^2}$

$F=$Gravitational force

$M=$Mass of the first body

$m=$Mass of the second body

$R=$The distance between the center of the two bodies.

$G=$The gravitational constant

1. Here, the value of $G=6.67\times {10}^{-11}\frac{N{m}^2}{{Kg}^2}$.
2. The value of $G$ is a very small value, so this is why the overall value of gravitational force decreases too much, so the gravitational force has a very small value. [Reason]

Hence, gravity is the weakest force.
