What is stronger, the strong nuclear force or electromagnetic (electric repulsion) force?*1 pointStrong nuclearElectromagnetic

To determine which force is stronger, the strong nuclear force or the electromagnetic (electric repulsion) force, we need to analyze the nature and characteristics of both forces.

1. Strong Nuclear Force: This is the force that holds protons and neutrons together in the nucleus of an atom. It is incredibly strong, but it acts over a very short range, approximately 1 femtometer (10^-15 meters). The strong nuclear force is what prevents protons, which repel each other due to the electromagnetic force, from flying apart due to their positive charge.

2. Electromagnetic Force: This force acts between charged particles. It can be attractive or repulsive; for example, it causes like charges (such as protons) to repel each other while opposite charges (like protons and electrons) attract each other. The electromagnetic force has an infinite range, but it is weaker than the strong nuclear force at very short distances.

Conclusion:

When comparing the two, the strong nuclear force is significantly stronger than the electromagnetic force, particularly at the small distances relevant to atomic nuclei.

Final Answer:

Strong nuclear force is stronger than electromagnetic force.
