A) 27/8
B) 8/27
C) 2/3
D) 3/2
Correct Answer: C
Solution :
The radii of a nuclei\[(R)\]varies with atomic number A as \[R=k{{A}^{1/3}}\] Given, \[{{A}_{1}}=8,\] \[{{A}_{2}}=27\] \[\therefore \] \[\frac{{{R}_{1}}}{{{R}_{2}}}=\frac{{{(8)}^{1/3}}}{{{(27)}^{1/3}}}=\frac{2}{3}\]You need to login to perform this action.
