A) 5 f
B) f
C) 25 f
D) \[\frac{f}{5}\]
Correct Answer: A
Solution :
The fundamental frequency is \[f=\frac{1}{2L}\sqrt{\frac{t}{M}}\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\frac{f'}{f}=\sqrt{\frac{T'}{T}}=\sqrt{\frac{25T}{T}}=5\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,f'=5f\]You need to login to perform this action.
