Question

The density of nuclear matter is:

Options

• Dependent on mass number A

• Equal to the density of an atom

• Approximately constant for all nuclei

• Proportional to A^2/3

Answer 1

Approximately constant for all nuclei

Explanation:

Since R ∝ A^1/3, volume ∝ A, and mass ∝ A, the ratio mass/volume = constant.

Nuclear density ≈ 2.3×10¹⁷ kg/m³.
