Question

The weakest forces of interaction among all classified fundamental forces are?

Answer 1

1. Forces are classified into four categories gravitational, electromagnetic, strong nuclear, and weak force.
2. Among these forces gravitational force has the lowest constant of proportionality $G=6.674\times {10}^{-11}{m}^{3}k{g}^{-3}{s}^{-2}$
3. Hence, gravitational force is the weakest of all classified fundamental forces.
