A) 6 : 10
B) 13 : 52
C) 40 : 177
D) 14 : 7
Correct Answer: A
Solution :
The radius of a nucleus of atomic number A is given by \[R={{R}_{0}}{{A}^{1/3}}\] where\[{{R}_{0}}\]is Bohrs radius. Given, \[{{A}_{1}}=27,\] \[{{A}_{2}}=125\] \[\therefore \] \[\frac{{{R}_{1}}}{{{R}_{2}}}={{\left( \frac{27}{125} \right)}^{1/3}}=\frac{3}{5}=\frac{6}{10}\]You need to login to perform this action.
