Which statements about nuclear radius and density are correct?

Question

G1 Physics · Accepted Answer

A is correct because empirical nuclear radius is R = R₀A¹ᐟ³. B is correct because V ∝ R³ ∝ A. C is correct because nuclear mass is approximately proportional to A and nuclear volume is also proportional to A, so their ratio is nearly constant. D is false because R² ∝ A²ᐟ³, not A. Correct answers: A, B and C.
