A horizontal metal wire is fixed on a state of tension between two vertical supports when plucked it gives a fundamental frequency `f_0`.
A `5.5 m` wire has a mass of `0.035 kg`,if the tension of the string is `77 N`,the speed of wave on the string is
a)`110 ms^(-1)`
b)`11sqrt10 ms^(-1)`
c)`77 ms^(-1)`
d)`11 ms^(-1)`
e)`102 ms^(-1)`.
