A) 2
B) 4
C) \[\sqrt{8}\]
D) 8
Correct Answer: A
Solution :
As, \[r\propto {{(A)}^{1/3}}\] \[{{A}_{He}}=4,\,\,{{A}_{s}}=32\] \[\therefore \,\,\,\,\,\,\,\,\,\frac{{{r}_{s}}}{{{r}_{He}}}={{\left( \frac{{{A}_{s}}}{{{A}_{He}}} \right)}^{1/3}}={{\left( \frac{32}{4} \right)}^{1/3}}={{\left( 8 \right)}^{1/3}}=2\]You need to login to perform this action.
