Definition: Nuclear force is one of the four fundamental forces of nature, the others being gravitational and electromagnetic forces. In fact, being 10 million times stronger than the chemical binding forces, they are also known as the strong forces. In this section, we will discuss this force in detail.
Nuclear force is the force that binds the protons and neutrons in a nucleus together. This force can exist between protons and protons, neutrons and protons or neutrons and neutrons. This force is what holds the nucleus together. The charge of protons, which is +1e,tends to push them away from each other with a strong electric field repulsive force, following Coulomb’s law. But nuclear force is strong enough to keep them together and to overcome that resistance at short range.
