The radius of a nucleus as measured by electron scattering is \(4.8 \mathrm{~fm}\). The mass number of nucleus is most likely to be
- A 16
- B 64
- C 46
- D 48
Answer & Solution
Correct Answer
(B) 64
Step-by-step Solution
Detailed explanation
The radius of a nucleus \(R\) is related to its mass number \(A\) by the formula \(R = R_{0} A^{1/3}\), where \(R_{0} \approx 1.2 \text{ fm}\). Given \(R = 4.8 \text{ fm}\), we have \(4.8 = 1.2 \times A^{1/3}\). Dividing both sides by \(1.2\), we get…
