Question

Assertion (A): Nuclear forces are always attractive. 

Reason (R): The nuclear force between protons and neutrons in a nucleus is a weak force.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Both Assertion (A) and Reason (R) are false.

Answer 1

Both Assertion (A) and Reason (R) are false.

Explanation:

Strong nuclear forces act between nucleons (protons and neutrons) within the nucleus. 

Main characteristics:

• Extremely strong but short-ranged
• Attractive at intermediate distances
• Repulsive at very small separations

Analyze Assertion

Nuclear force is not always attractive. When nucleons come very close, the force becomes repulsive to prevent the nucleus from collapsing.

Therefore, Assertion (A) is false.

Analyze Reason

The nuclear force is actually the strongest fundamental force, not a weak one. The weak force is a separate interaction responsible for processes like beta decay.

Hence, Reason (R) is false.
