Which best describes Yanni’s error? Only the weak force is active in the nuclei of atoms.
The weak force keeps particles that make up neutrons together.
The strong force overcomes repulsion and keeps protons together.
The strong force is responsible for radioactive decay.

the strong force that overcomes repulsion and keeps protons together

Explanation:

The nucleus of an atom are made up of protons and neutrons. The protons habe positive charges while the neutrons have no charge. As a result of this, there is an electrostatic force of repulsion that exist within the nucleus.

Therefore, from the chart given which was meant to compare the strong and weak forces, Yanni's error was the strong force that overcomes repulsion and keeps protons together
