Question

Gravitational force is the weakest force in nature. Explain.

Answer 1

Gravitational Force is the weakest among all the four fundamental forces because of the Gravitational constant.

The universal Gravitational constant has a tiny value, as compared to the value of the electrostatic constant in a vacuum. As given by Newton, the formula for force between two masses can be given by $F=\frac{GMm}{R^2}$while the Coulomb’s force between two electrically charged bodies is given by$F=\frac{KQq}{R^2}$ and we all know that the value of G $(6.67\times {10}^{-11})$is quite less than that of K$(9\times {10}^9)$.this is a preliminary explanation of the weakness of the Gravitational force with respect to the Electromagnetic force.
