Answer to Problem 1Q

The fundamental interaction is the weak interaction.

Explanation of Solution

There are four fundamental interactions. They are gravitational, electromagnetic, strong and weak interactions. Among these, gravitational interaction is significant at larger distance only. Electromagnetic interaction must be between the charged entities only. Strong interaction is significant inside nucleus only. The remaining one is the weak interaction and it is responsible for the decay of neutron outside nucleus.

Therefore, the fundamental interaction is the weak interaction.

(b)

To determine

The fundamental interaction responsible for the attraction between proton and neutrons inside the nucleus.

Answer to Problem 1Q

The fundamental force is the strong interaction.

Explanation of Solution

Among the four fundamental interactions, the force which is predominant inside nucleus is the strong force. It is significant in the order of femtometers. That is, this force is negligible outside the nucleus. It is the force that binds nucleons inside the nucleus, that is which hold protons and neutrons together.

Therefore, the fundamental force is the strong interaction.

(c)

To determine

The fundamental interaction responsible for the pulling of moon by Earth.

Answer to Problem 1Q

The fundamental force is the gravitational interaction.

Explanation of Solution

Among the four fundamental interactions, the force which is predominant at large distance is the gravitational interaction. There will be gravitational force of attraction between any two bodies having non zero rest mass. But the force become significantly stronger only for huge masses. In case of Earth and moon, since their mass are very huge, gravitational force plays the role in pulling the moon by Earth.

Therefore, the fundamental force is the strong interaction.

(d)

To determine

The fundamental interaction responsible for the repulsion between protons inside nucleus.

Answer to Problem 1Q

The fundamental force is the electromagnetic interaction.

Explanation of Solution

Among the four fundamental interactions, the force which is predominant between charged entities is the electromagnetic interaction. Proton is a charged particle. It can be of two kinds-attractive or repulsive. Like charges attracts each other, while unlike charges repel each other.

Therefore, the fundamental force is the strong interaction.
