A) \[1:\sqrt{2}:\frac{1}{\sqrt{2}}\]
B) \[2:\sqrt{2}:\frac{1}{\sqrt{2}}\]
C) \[\frac{1}{\sqrt{2}}:2:1\]
D) \[2:\frac{1}{\sqrt{2}}:1\]
Correct Answer: A
Solution :
\[T\propto \frac{1}{\sqrt{k}}\]Þ \[{{T}_{1}}:{{T}_{2}}:{{T}_{3}}=\frac{1}{\sqrt{k}}:\frac{1}{\sqrt{k/2}}:\frac{1}{\sqrt{2k}}=1:\sqrt{2}:\frac{1}{\sqrt{2}}\]
