A) 3 Fermi
B) 4 Fermi
C) 5 Fermi
D) 6 Fermi
Correct Answer: D
Solution :
\[R={{R}_{0}}{{A}^{1/3}}\] \[\therefore \] \[\frac{{{R}_{1}}}{{{R}_{2}}}={{\left( \frac{{{A}_{1}}}{{{A}_{2}}} \right)}^{1/3}}\] \[\frac{2}{{{R}_{2}}}={{\left( \frac{7}{189} \right)}^{1/3}}\] \[\Rightarrow \] \[{{R}_{2}}=6\,Fermi\]You need to login to perform this action.
