Question

The potential energy between two nucleons inside a nucleus is minimum at a distance of about ______.

Options

• 0.8 fm

• 1.6 fm

• 2.0 fm

• 2.8 fm

Answer 1

The potential energy between two nucleons inside a nucleus is minimum at a distance of about 0.8 fm.

Explanation:

In a nucleus, the potential energy between two nucleons is lowest at a distance of roughly 0.8 fm. The force turns repulsive as the distance decreases.
