The nuclei of most atoms contain multiple protons. each proton has a positive charge. if objects that have like charges repel each other, why do the protons in the nuclei of most atlms not fly apart?

a. the charges of protons and neutrons cancel each other out.

b. electrons outside the nucleus push on protons.

c. a strong nuclear force between an atom's protons and neutrons holds together the atom's nucleus.

Option (C) is the correct answer.

Explanation:

Despite of having same charge on protons they are bounded together inside the nucleus of an atom. The force which binds protons and neutrons together in a nucleus is known as strong nuclear binding energy.

This nuclear binding energy is strong enough to overcome the electrostatic force of repulsion between the protons.

Therefore, we can conclude that the protons in the nuclei of most atoms not fly apart because a strong nuclear force between an atom's protons and neutrons holds together the atom's nucleus.

i think it's c. i'm not sure but i think so.
