Question

1. how does the strong nuclear force hold the nucleus of an atom together? (1 point)

it overcomes the electrical force of repulsion between protons in the nucleus.
it overcomes the electrical force of attraction between protons in the nucleus.
it overcomes the electrical force of repulsion between electrons in the nucleus.

Explanation:

Protons in the nucleus are positively charged. Like charges repel each other (electrical force of repulsion). The strong nuclear force is a short - range force that acts between nucleons (protons and neutrons). It is stronger than the electrical repulsion between protons at very short distances (within the nucleus). Electrons are not in the nucleus (they are in electron shells around the nucleus). The electrical force between protons is repulsive, not attractive.

Answer:

It overcomes the electrical force of repulsion between protons in the nucleus.
