The correct answer is Option (1) →independent of the nuclear charge
Nuclear force is:
-
The force that binds protons and neutrons (collectively called nucleons) within the nucleus.
-
It is independent of the nuclear charge (i.e., does not depend on the electric charge).
-
It is a short-range but very strong attractive force.
-
It does not act between electrons and protons—that interaction is electromagnetic, not nuclear.
Option 1: "independent of the nuclear charge"
This is correct and aligns with the properties of nuclear forces.
-
Option 2 is partially correct, but nuclear forces do depend somewhat on the spin of nucleons.
-
Option 3 is incorrect because it describes the weak nuclear force, not the strong nuclear force.
-
Option 4 is completely incorrect, as it describes electromagnetic attraction between electrons and protons, not nuclear force.
