Concept:Nuclear force is a short-range, strong, charge-independent, and non-central force between nucleons.
Explanation:The strong nuclear force has a very short range, about
1–
2 fm (femtometers), so Option A is false.
It is the strongest of the four fundamental forces at that scale, not the weakest – Option B is false.
Nuclear force has both a central part,
V(r), and a tensor (spin-dependent) part; it cannot be fully described by a central potential alone, making it a
non-central force – Option C is true.
The force is nearly identical for
pp,
nn, and
np interactions, meaning it does not depend on the electric charge of the nucleons – Option D is false.
Answer:Option C: Nuclear force is a non‑central force.
