Type: MCQ-numerical-Medium
If the nucleus of ²⁷₁₃Al has a nuclear radius of about 3.6 fm, then ¹²⁵₅₂Te would have its radius approximately as
A
9.6 fm
B
12 fm
C
4.8 fm
D
6 fm
Correct Answer
Option D
Detailed Explanation
The nuclear radius is proportional to the cube root of the mass number. Using the formula R₂ = R₁ × (A₂/A₁)^(1/3), we find R₂ = 3.6 × (125/27)^(1/3) = 6 fm.
