Question

the strong force is the force responsible for keeping the number of neutrons higher than the number of protons in the nucleus of an atom. keeping protons and neutrons together in the nucleus of an atom. this is difficult because the protons being all the same charge will want to repel.

Explanation:

The strong force in physics (subfield of Natural Science) is responsible for binding protons and neutrons in an atomic nucleus, overcoming proton-proton repulsion. The first option is incorrect as the strong force doesn't regulate neutron - proton number ratio.

Answer:

keeping protons and neutrons together in the nucleus of an atom. This is difficult because the protons being all the same charge will want to repel.
