Which of the following statements is true for nuclear forces?

1. they obey the inverse square law of distance
2. they obey the inverse third power law of distance
3. they are short range forces
4. they are equal in strength to electromagnetic forces

Correct answer: they are short range forces

Solution

Nuclear forces are short-range forces, meaning they act only over distances comparable to the size of an atomic nucleus. They do not follow an inverse square or third power law like gravitational or electromagnetic forces.
