alleryNuclear radius R relates to mass number A as:
AR = R₀ × A
BR = R₀ A^(1/3) (where R₀ ≈ 1.2 × 10⁻¹⁵ m)
CR = A²
DR ∝ A
Answer & Solution
Correct answer: B. R = R₀ A^(1/3) (where R₀ ≈ 1.2 × 10⁻¹⁵ m)
R = R₀ A^(1/3), R₀ ≈ 1.2 fm.
Volume ∝ R³ ∝ A (constant density of nucleus, ~10¹⁷ kg/m³).
All nuclei have similar density.
