AIPMT PRELIMS 2012 Physics Nuclear Size MCQ Question
Type: MCQ-numerical-Medium-Class 12
If the nuclear radius of ²⁷Al is 3.6 Fermi, the approximate nuclear radius of ⁶⁴Cu in Fermi is:
A
3.6
B
2.4
C
1.2
D
4.8
Correct Answer
Option D
Detailed Explanation
The nuclear radius R is proportional to A^(1/3). Calculating for ⁶⁴Cu using the given radius for ²⁷Al gives R ≈ 4.8 F.
