Given below are two statements:
Assertion (A): The nuclear force is charge-independent and acts equally between proton-proton, neutron-neutron, and proton-neutron pairs.
Reason (R): Nuclear forces are short-range forces and are primarily attractive, responsible for the stability of the nucleus.

Question

Given below are two statements:

Assertion (A): The nuclear force is charge-independent and acts equally between proton-proton, neutron-neutron, and proton-neutron pairs.

Reason (R): Nuclear forces are short-range forces and are primarily attractive, responsible for the stability of the nucleus.

TestHub · Accepted Answer

Assertion (A) is true: nuclear forces are indeed charge-independent, meaning their strength does not depend on the charge of the nucleons.

Reason (R) is also true: nuclear forces are short-range and primarily attractive, which is crucial for holding the nucleus together. However, the short-range and attractive nature (R) does not directly explain *why* they are charge-independent (A). These are distinct properties of the nuclear force.
