Answer:
Step-by-step explanation:
The nucleus of an atom contains both proton(s) and neutron(s). The protons are positively charged while the neutrons have no charge; hence the nucleus is positively charged. Generally, like charges repel, thus protons in the nucleus should ordinarily repel each other and fly apart in the nucleus but there is a stronger force (than the electrical force) that pulls the protons and neutrons toward each other (at some distance and does not bind them together). This force is known as the nuclear force.
