The density of a nucleus of mass number A is proportional to :
- A \( A^3 \)
- B \( A^{1/3} \)
- C \( A \)
- D \( A^0 \)
Answer & Solution
Correct Answer
(D) \( A^0 \)
Step-by-step Solution
Detailed explanation
\( R \propto A^{1/3} \) \( \rho = \frac{m}{V} \propto \frac{A}{(A^{1/3})^3} \) \( \rho \propto \frac{A}{A} \propto A^0 \)
