A) Plucked at \[\frac{l}{4}\] and touch at \[\frac{l}{2}\]
B) Plucked at \[\frac{l}{4}\] and touch at \[\frac{3l}{4}\]
C) Plucked at \[\frac{l}{2}\] and touched at \[\frac{l}{4}\]
D) Plucked at \[\frac{l}{2}\] and touched at \[\frac{3l}{4}\]
Correct Answer: A
Solution :
Second harmonic means 2 loops in a total length Hence plucking distance from one end \[=\frac{l}{2p}=\frac{l}{2\times 2}=\frac{l}{4}.\]You need to login to perform this action.
