Assertion (A) : Nuclear Force is much stronger than Coulombic Force. Reason (R) : Nuclear Force is short-ranged.

(A) and (R) are both true and (R) is the correct explanation of (A). (A) and (R) are both true but (R) is NOT the correct explanation of (A). One of the two is true. Both are false.

(A) and (R) are both true but (R) is NOT the correct explanation of (A).

Nuclear force binds electrically repulsive protons and electrically neutral neutrons to drastically small region of the order of 10-15 m . Thus, the nuclear force is short-ranged.
