GENERAL KNOWLEDGE

Detailed explanation-1: -Repulsive forces exists between two protons outside the nucleus.

Detailed explanation-2: -The Nuclear Force. 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.

Detailed explanation-3: -Since most macroscopic objects are neutral, they have an equal number of protons and electrons. The attractive force between the electrons in one body and the protons in the other body is exactly canceled by the repulsive force between the electrons in the two bodies.

Detailed explanation-4: -That is called strong nuclear force. It is one of the fundamental forces. The amount of strong nuclear force acting between two protons is the same as the amount of strong nuclear force acting between two neutrons.

Detailed explanation-5: -The force between two protons is same as the force between proton and neutron and this force is a strong nuclear force-one of the four fundamental forces of nature. It is also the strongest force of the four.
