Nucleus: Practice Problem & Solution

Which of the following statements is true for nuclear forces? (1990)
They obey the inverse square law of distance.
They obey the inverse third power law of distance.
They are short range forces.
They are equal in strength to electromagnetic forces.

Solution Explained:

To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:

Nuclear forces are the strongest forces in nature but they are strictly short-range forces, operating effectively only over distances of about 2 to 3 femtometers (fm). They do not follow the inverse square law.
