A) \[{{f}_{0}}\]
B) \[3{{f}_{0}}/4\]
C) \[2{{f}_{0}}\]
D) \[{{f}_{0}}/2\]
Correct Answer: A
Solution :
\[{{f}_{0}}=\frac{V}{2l}\]for both end open. Now one end open and one end closed. \[{{f}_{0}}=\frac{V}{4l}\] \[l=l/2\] \[{{f}_{0}}=\frac{V}{4l/2}=\frac{V}{2l}\] \[\therefore \] \[{{f}_{0}}={{f}_{0}}\]You need to login to perform this action.
