Question

Write any two features of nuclear forces.

Hint:

Remember: Nuclear forces are strong, short-range, and saturating. Writing any two standard properties is sufficient for full marks.

Answer 1

Features of Nuclear Forces
1. Short-Range Force: Nuclear forces act only over very short distances, approximately \( 10^{-15} \, \text{m} \) (1 femtometer), which is roughly the size of a nucleus. Beyond this range, their effect becomes negligible.
2. Charge Independence: Nuclear forces are almost the same between two protons, two neutrons, or a proton and a neutron. They depend mainly on the distance between nucleons and not on their electric charge.
Additional notes:
- Nuclear forces are attractive at short distances to hold the nucleus together but become repulsive at very short distances to prevent collapse.
- They are much stronger than electromagnetic forces within the nucleus but act only at nuclear scales.
