Which best describes the weak nuclear force? it maintains attraction between the molecules in liquids. it attracts the nucleus of one atom to the nucleus of another atom. it pulls all matter in the universe together. it keeps particles that make up protons and neutrons together.

It keeps particles that make up protons and neutrons together.

Explanation:

Nuclear force is a short range of force which means it will act at short range of distance like fermi order distance.

This shows the order of radius of the nuclei which means all the neutrons and protons which resides into the nucleus will exert the nuclear force on each other and this nuclear force is of large magnitude compare to electrostatic force or gravitation force between them.

While if the distance is more than the fermi order distance then the nuclear force totally disappears so it will not exist for large distances.

so here the correct answer must be

It keeps particles that make up protons and neutrons together.
