Chapter 39, Problem 3A

To determine

The particles between which the strong nuclear force acts.

Explanation of Solution

Introduction:

The subatomic particles are electron, proton and neutron. These subatomic particles form the atomic structure. The electrons are dispersed in the different orbits around the nucleus.

The proton and neutron are known as nucleons and are bound in the nucleus. The strong nuclear force acts between the nucleons. Strong nuclear force is of very short range i.e. ${10}^{-15}\text{ m}$ . This force is responsible to bound the nucleons inside the nucleus. As its name suggests, it is very strong in nature.It acts between the proton − proton, proton - neutron, and neutron − neutrons.

Conclusion:

Thus, the strong nuclear force acts between the protons and neutrons.
