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.
