**[SOLVED] length of wire**

## Homework Statement

A wire of mass 1.1 g is under a tension of 100 N. If its third overtone is at a frequency of 750 Hz, calculate the length of the wire.

## The Attempt at a Solution

v = sqrt(FL/m) = 301.5*sqrt(L)

f

_{n}= n*v/(2*L) --> L = n*v/(2*f

_{n}) -->

__L = 0.36 m__

The book says

__0.65 m__. Am I wrong?
