Atoms And Nuclei Question 264
Question: If radius of the $ _{13}^{27}Al $ nucleus is estimated to be 3.6 Fermi then the radius of $ _{52}^{125}Te $ nucleus be nearly [AIEEE 2005]
Options:
A) 4 Fermi
B) 5 Fermi
C) 6 Fermi
D) 8 Fermi
Show Answer
Answer:
Correct Answer: C
Solution:
$ r\propto {{A}^{1/3}} $
Þ $ \frac{r_{1}}{r_{2}}={{( \frac{A_{1}}{A_{2}} )}^{1/3}} $
Þ $ \frac{3.6}{r_{2}}={{( \frac{27}{125} )}^{1/3}}=\frac{3}{5} $
Þ $ r_{2}=6,Fermi $
