A) 1 : 3
B) 1 : 9
C) 1 : 6
D) 1 :8
Correct Answer: B
Solution :
\[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{1}{27}\,\Rightarrow \,{{\left( \frac{{{x}_{1}}}{{{x}_{2}}} \right)}^{3}}\,=\frac{1}{27}\] \[\Rightarrow \,\,\frac{{{x}_{1}}}{{{x}_{2}}}=\frac{1}{3}\] Required ratio \[=\frac{{{x}_{1}}^{2}}{{{x}_{2}}^{2}}\,={{\left( \frac{1}{3} \right)}^{2}}=1:9\]You need to login to perform this action.
