QAIPMT-2007-Ph-2338: NEET 2007 Physics - Class 12 AIPMT-2007-Ph-2338 Solution: If the nucleus \(_{13}^{27}Al\) has a nuclear radius of about…
If the nucleus has a nuclear radius of about 3.6 fm, then would have its radius approximately as
Multiple Choice Options
- A 9.6 fm
- B 12.0 fm
- C 4.8 fm
- D 6.0 fm
Step-by-Step Verified Solution
A nucleus of mass
number A has radius
R = R 0 A 1/3 ,
where R 0 = 1.2 _ 10 �15 m
and A = mass number
For 13 27 A l , R 1 = R 0 (27) 1/3 = 3R 0
For 32 125 T e , R 2 = R 0 (125) 1/3 = 5R 0
_ R 2 R 1 = 5 R 0 3 R 0
_ R 2 = 5 3 _ R 1 = 5 3 _ 3.6 = 6.0 fm
