A) 300 Hz
B) 500 Hz
C) 1000 Hz
D) 400 Hz
E) 600 Hz
Correct Answer: A
Solution :
\[n=\frac{1}{2l}\sqrt{\left( \frac{T}{m} \right)}\] \[\therefore \] \[n+\frac{3}{2}=\frac{1}{2l}\sqrt{\left( \frac{101T}{100m} \right)}\] \[=1.005\times \frac{1}{2l}\sqrt{\left( \frac{T}{m} \right)}\] \[\Rightarrow \] \[n+1.5=1.005\,n\] \[\Rightarrow \] \[n=300\,Hz\]You need to login to perform this action.
