A) 300Hz
B) 500Hz
C) 100Hz
D) 400Hz
Correct Answer: A
Solution :
[a] \[f=\frac{1}{2\pi }\sqrt{\frac{T}{\overset{o}{\mathop{\mu }}\,}}\] \[f\propto \sqrt{T}\] \[\frac{f-f}{f}\times 100K\frac{\sqrt{T-T}}{\sqrt{T}}\times 100\] \[\frac{3}{2{{f}_{o}}}=\frac{1}{2}\times 1%\] \[{{f}_{o}}=300Hz\]You need to login to perform this action.
