Two nuclei have their mass numbers in the ratio of 1: 3 . The ratio of their nuclear densities would be

Step-by-step solution

Density of nuclear matter is independent of mass number, so the required ratio is 1: 1 . Alternative : A₁: A₂=1: 3 Their radii will be in the ratio gathered R₀ A₁^ 1 / 3 : R₀ A₂^ 1 / 3 =1: 3^ 1 / 3 Density = A 4 3 R^3 _ A₁ : _ A₂ = 1 4 3 R₀^3 1^3 : 3 4 3 R₀^3 (3^ 1 / 3 )^3 gathered Their nuclear densities will be the same.
