Why do protons tend to repel one another what is the key to getting them to stick together?

Explanation:

Between protons there is a force of repulsion, this is due to Coulomb's law, which states that two charges that have the same sign, experiences a repulsive force.

The strong nuclear force is responsible for holding together the protons that coexist in the atomic nucleus, overcoming the electromagnetic repulsion between them.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
