The strongest force in the nature is

The correct answer is Option (2) → Nuclear force

Nature has four fundamental forces. Their relative strengths, taking the strong nuclear force as 1, are roughly:

    \( \text{Strong nuclear force: } 1 \)
    \( \text{Electromagnetic force: } 10^{-2} \)
    \( \text{Weak nuclear force: } 10^{-13} \)
    \( \text{Gravitational force: } 10^{-39} \)

The strong nuclear force, which binds protons and neutrons in a nucleus, is therefore the strongest, even though it acts only over distances of a few femtometres. Electrostatic and magnetic forces are both parts of the electromagnetic force, and gravitation is the weakest of all.

NCERT (2026-27):
Nuclear Force – “… (i) The nuclear force is much stronger than the Coulomb force acting between charges or the gravitational forces between masses. … The gravitational force is much weaker than even Coulomb force.”
