Do two protons attract or repel? This is a fundamental question in the field of physics, as it deals with the behavior of subatomic particles. To understand the answer, we need to delve into the concept of the strong nuclear force and the electromagnetic force, which are the two fundamental forces at play in the universe.
The strong nuclear force is one of the four fundamental forces of nature, responsible for holding protons and neutrons together within the atomic nucleus. This force is incredibly powerful, overcoming the electromagnetic repulsion between positively charged protons. However, the strong nuclear force has a very short range, acting only within the tiny space of the nucleus.
On the other hand, the electromagnetic force is the force that governs the interactions between charged particles, such as protons. It is this force that causes like charges to repel each other. Since protons are positively charged, they naturally repel one another due to the electromagnetic force.
So, when we ask whether two protons attract or repel, the answer is that they repel each other. This repulsion is what prevents atoms from collapsing under the influence of the electromagnetic force. However, the strong nuclear force can overcome this repulsion and keep the nucleus together.
In summary, while two protons do repel each other due to the electromagnetic force, the strong nuclear force is strong enough to hold them together within the atomic nucleus. This delicate balance is crucial for the stability of atoms and the existence of matter as we know it.
