Hint: The Big bang theory states that from the first second of the universe, all matter that exists was broken down into subatomic particles. The strong and weak nuclear forces are pulled together by quarks.
Complete step by step answer:
There were only two basic forces known from the beginning. They are gravitational force and electromagnetic force. It was believed that forces that are caused inside the atoms are due to the electromagnetic force. This particular force is also responsible for the binding of the nucleus inside the atom. It is hard to understand the forces inside the nucleus. The forces inside the nucleus can be explained with the help of the theory of the quarks. The nuclear forces can be divided into two types. They are a strong nuclear force and the weak nuclear force.
the strong nuclear force is responsible for binding the nucleons in the nucleus. It is the strongest of all the forces. It is this force that keeps several protons together in a nucleus against the strong electrical force of repulsion. It is relatively short-ranged. It is the main force in the reactions and decays of most of the elementary particles. The particles that mediate the strong interaction between the quarks are called gluons. The particles that participate in the strong interactions are called hadrons which include protons, neutrons, mesons, and many other elementary particles.
The weak interaction is responsible for the beta decay by nuclei and the decay of some heavier particles. It has a range that is smaller than the 0.001fm. weak interactions are useful for understanding the properties of certain elementary particles. The electroweak theory unified electromagnetic and weak interactions. All have spin one. The electromagnetic and weak forces act independently except at extremely high particle energies.
Note:
The relative strength of an interaction decides the time scale over which it acts. A shorter time is sufficient for a force to cause decay or a reaction. In the case of the weak force, a longer time is required. Hence the mean lifetime is an index of the type of interaction responsible for the process.
