Question

Quizplus · Accepted Answer

Protons and neutrons are held together by the strong interaction, which is one of the four fundamental forces of nature. This force is responsible for binding quarks together to form protons and neutrons, and for holding protons and neutrons together in the nucleus. None of the other choices - gravitational, weak, or electromagnetic interactions - are strong enough to hold together the nucleus of an atom.
