Write any two features of nuclear forces.

Solution 1
- Nuclear forces are much stronger then coulomb forces acting between charges or the gravitational forces between masses.
- The nuclear force between neutron-neutron, proton-neutron, and proton-proton is approximately the same. The nuclear force does not depend on the electric charge.
Solution 2
- Short range: Nuclear forces act only over small distances (about 1-2 femtometers). Beyond many femtometres, they become negligible.
- Very strong in nature: They are the strongest known forces in nature at short distances, overcoming the electrostatic repulsion between protons.
- Charge independent (similar for p-p, n-n, p-n interactions).
- Saturation property (each nucleon interacts only with nearby nucleons).
- Attractive at intermediate range and repulsive at very short distances.
