Which of the following statements is true for nuclear forces?

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.

Range: Nuclear forces (strong interaction) are effective only over very short distances, typically of the order of femtometers ( $10^{-15}$ m). Beyond this range, they drop to zero rapidly. This explains why nucleons are compactly held inside the nucleus .
Law of Distance: Unlike gravitational and electrostatic forces, nuclear forces do not obey the inverse square law ( $F \propto 1/r^2$ ). Their dependence on distance is much more complex.
Strength: Within their effective range, nuclear forces are the strongest fundamental forces in nature, being approximately 100 times stronger than electromagnetic forces and much stronger than gravitational forces.
