Nuclei

Question:

Binding Energy per nucleon is constant. Which of the following best describes the cause of it?

Options:

Nucleus is a dense mass consisting of nucleons.

The forces are saturated to a given distance after which they fall to zero.

The binding energy in nucleons is very large.

The forces are zero upto a given distance after which they begin to rise.

Correct Answer:

The forces are saturated to a given distance after which they fall to zero.

Explanation:

The nuclear forces between two charges fall to zero as distance between then is few fermimeters(10-15 m). This leads to saturation of forces in a medium or large sized nucleus, whcih is the reason that the binding energy per nucleon is constant.
