Question

Why is gravitational force the weakest force in nature?

Answer 1

Gravitational force:

1. Because of the Gravitational Constant, the Gravitational Force is the weakest of the four fundamental forces.
2. When compared to the magnitude of the electrostatic constant in a vacuum, the universal gravitational constant has a low value.
3. The formulas $\mathrm{F}=\frac{\mathrm{GMm}}{{\mathrm{R}}^2}$ and $\mathrm{F}=\mathrm{k}\frac{{\mathrm{q}}_1{\mathrm{q}}_2}{{\mathrm{R}}^2}$ represent the gravitational force between two masses and Coulomb's force between two electrically charged bodies, respectively. The value of $\mathrm{G}(6.67\times {10}^{-11})$ is very less than that of $k(9.0\times {10}^9)$. This is just an example that states why the gravitational force is weaker than the electromagnetic force.

Therefore, the gravitational force is the weakest force in nature.
