Question

The fundamental force in nature which operates among heavier elementary particles only is

• A. Strong nuclear force
• B. Electromagnetic force
• C. Gravitational force
• D. Weak nuclear force

Hint:

Remember: Strong force → nucleons, weak force → beta decay, gravitational → all masses, electromagnetic → charged particles.

Answer 1

The Correct Option is A

Strong nuclear force acts between nucleons (protons and neutrons) to hold the nucleus together. It is effective only at very short distances $10^{-15}~\text{m}$ and is stronger than electromagnetic and gravitational forces.
