A) decrease by 2 times
B) decrease by 4 times
C) increase by 4 times
D) increase by 2 times
Correct Answer: A
Solution :
We have \[\lambda =\frac{12.27}{\sqrt{V}}\] So, \[\frac{{{\lambda }_{1}}}{{{\lambda }_{2}}}=\sqrt{\frac{{{V}_{2}}}{{{V}_{1}}}}\] \[{{\lambda }_{2}}={{\lambda }_{1}}\sqrt{\frac{{{V}_{1}}}{{{V}_{2}}}}\] \[{{\lambda }_{2}}={{\lambda }_{1}}\sqrt{\frac{25}{100}}\] \[{{\lambda }_{2}}={{\lambda }_{1}}\sqrt{\frac{1}{4}}=\frac{{{\lambda }_{1}}}{2}\]
