Detailed explanation-1: -The strong nuclear force is a strong attractive force, but only activates when you bring the nucleons closer to each other than a few femtometers. At these length scales, no force in the universe is stronger than the strong nuclear force.
Detailed explanation-2: -So, the weak force is not a force in the sense of attraction and repulsion. It is key to radioactive decay and the nuclear fusion process taking place in stars.
Detailed explanation-3: -The strongest attractive force is nuclear force.
Detailed explanation-4: -The strong nuclear force is a very strong, attractive short-range (10-15 m) force that binds the protons and neutrons in the nuclei of atoms together. It is the strongest of the fundamental forces, but acts over a very short distance (10-15 m).
Detailed explanation-5: -The nuclear force acts between all of the particles in the nucleus, i.e., between two neutrons, between two protons, and between a neutron and a proton. It is attractive in all cases. In contrast, an electrical force acts only between two protons and it is repulsive.
