Question

The strong nuclear force is:

• A. Always Attractive
• B. Always Repulsive
• C. Attractive when nucleons are very close and vice versa
• D. Repulsive when nucleons are very close and vice versa

Answer 1

The correct option is D Repulsive when nucleons are very close and vice versa

Yes yes, I know, the strong nuclear force is an odd kinda force. So, what we have studied is: it is repulsive when nucleons are very close, then it becomes attractive and after a very short distance it drops off to zero. But within that short distance, it is way stronger than any other force in the universe.
