Question

what happens to the strong nuclear force when two nucleons are very close to each other? it becomes weaker. it becomes repulsive. it remains constant. it disappears completely.

Explanation:

The strong nuclear force is attractive at medium - range distances between nucleons. But when two nucleons get very close (at extremely short distances), the strong nuclear force becomes repulsive due to the Pauli exclusion principle and the nature of the interaction between quarks within the nucleons.

Answer:

It becomes repulsive.
