Question
Write any three characteristics of nuclear force.
✓
Answer
(i) The nature of nuclear force is attractive.
(ii) Nuclear force is a short-range force. This force becomes negligible when the distance between nucleons is more than $1 \times 10^{-14}$ meters. This force remains effective only at distances less than this. Therefore it is called short range force.
(iii) Nuclear force is very strong. At a distance of $2 \times 10^{-15}$ meters the nuclear force is about 100 times the electric force.
(iv) The nature of nuclear force becomes repulsive at a distance of $0.5 \times 10^{-15}$ metres.
(v) Nuclear force does not depend on charge. Therefore, it occurs equally between proton-neutron or proton-proton or neutron-neutron. Due to this nature of nuclear force, the question of the stability of the nucleus is solved.
