AIPMT PRELIMS 2007 Physics Nuclear Radius MCQ Question
Type: MCQ-numerical-Medium-Class 12
If the nucleus ²⁷₁₃Al has nuclear radius of about 3.6 fm, then ¹²⁵₅₂Te would have its radius approximately as
A
9.6fm
B
12.0fm
C
4.8fm
D
6.0fm
Correct Answer
Option B
Detailed Explanation
Nuclear radius is proportional to the cube root of the mass number (A). R₂/R₁ = (A₂/A₁)^(1/3). For ¹²⁵Te, R = 3.6 × (125/27)^(1/3) ≈ 6.0 fm.
