If the ratio of the mass numbers of two nuclei is \(27: 125\), then the ratio of their surface areas is
- A \(3: 5\)
- B \(9: 25\)
- C \(27: 125\)
- D \(1: 1\)
Answer & Solution
Correct Answer
(B) \(9: 25\)
Step-by-step Solution
Detailed explanation
\( \frac{S_1}{S_2} = \left(\frac{A_1}{A_2}\right)^{2/3} \) \( \frac{S_1}{S_2} = \left(\frac{27}{125}\right)^{2/3} = \left(\frac{3}{5}\right)^2 = \frac{9}{25} \)
