A) 5 Hz
B) 15 Hz
C) 10 Hz
D) 2 Hz
Correct Answer: A
Solution :
Frequency of vibration is given by \[n=\frac{p}{2l}\sqrt{\frac{T}{m}}\] \[\left( \text{where}\,\,v=\sqrt{\frac{T}{m}} \right)\] \[\therefore \] \[n=\frac{pv}{2l}=\frac{5\times 20}{2\times 10}=5\,\,Hz\]You need to login to perform this action.
