Question

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

• A. 0.8 fm
• B. 1.6 fm
• C. 2.0 fm
• D. 2.8 fm

Hint:

The minimum potential energy between nucleons in a nucleus corresponds to the equilibrium separation where the nuclear force is most effective at holding the nucleons together.

Answer 1

The Correct Option is A

Within a nucleus, the nuclear potential models the interaction between two nucleons, incorporating both attractive and repulsive forces. At greater separations, the attractive force prevails. Conversely, at very short distances, the repulsive force becomes significant, attributed to the Pauli exclusion principle and other quantum phenomena.
The point of minimum potential energy is reached when the attractive and repulsive forces achieve equilibrium. This equilibrium is typically observed at a nucleon separation of approximately 0.8 femtometers (fm), representing the distance where nuclear forces exert their maximal influence.
