A) \[{{A}^{3/4}}\]
B) \[{{A}^{2/3}}\]
C) \[{{A}^{1/3}}\]
D) \[{{A}^{5/3}}\]
Correct Answer: C
Solution :
Nuclear radius is proportional to \[{{A}^{1/3}}\], where A is the mass number of nucleus, ie, \[R\propto {{A}^{1/3}}\]. \[\Rightarrow R={{R}_{0}}{{A}^{1/3}}\]. where \[{{R}_{0}}=1.2\times {{10}^{-15}}m\]
