Question

1. What interactions affect protons in an atomic nucleus? More than one answer may be correct.

Answer 1

A=
In the nature there are four fundamental forces, namely nuclear force, electromagnetic force, weak force, and gravitational force. These forces are arranged with respect to their strengths in descending order.
The nuclear forces are of greater strengths.
These bind up the protons and the neutrons in an atom together. The nuclear forces are strong enough to combine the quarks that form the nucleons.

B= The weak forces of the interaction are the forces that are short ranged and cause the instability of the nucleus. These are 1/10^5 times of the nuclear forces.

C= The electromagnetic forces are the forces that which combine the atoms and the molecules that intend form the ordinary matter. The electromagnetic forces are 1/10^5times of the nuclear forces.

D= The gravitational forces are 1/10^5 times of the nuclear force.
