A) 100 Hz
B) 200 Hz
C) 256 Hz
D) 400 Hz
Correct Answer: B
Solution :
As we know plucking distance from one end \[=\frac{l}{2p}\] Þ \[25=\frac{100}{2p}\] Þ \[p=2\]. Hence frequency of vibration \[n=\frac{p}{2l}\sqrt{\frac{T}{m}}=\frac{2}{2\times 1}\sqrt{\frac{20}{5\times {{10}^{-4}}}}\] = \[200Hz.\]You need to login to perform this action.
