Question

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

G1 Physics · Accepted Answer

Nuclear mass M ∝ A. Nuclear volume V = (4/3)πR³ ∝ A because R ∝ A¹ᐟ³. Thus nuclear density ρ = M/V is approximately constant independent of A. Final answer: Option D (1 : 1).
