A) 240 Hz
B) 230 Hz
C) 220 Hz
D) 200 Hz
Correct Answer: A
Solution :
\[n=\frac{p}{2l}\sqrt{\frac{T}{m}}\propto \sqrt{T}\]Þ \[\frac{{{n}_{1}}}{{{n}_{2}}}=\sqrt{\frac{{{T}_{1}}}{{{T}_{2}}}}\] Þ\[\frac{260}{{{n}_{2}}}=\sqrt{\frac{50.7g}{(50.7-0.0075\times {{10}^{3}})g}}\]Þ\[{{n}_{2}}\approx 240\]You need to login to perform this action.
