Frequency of fundamental and overtones in a guitar string

[pupatel]

A guitar string is 90 cm long and has a mass of 3.6 g. From the bridge to the support post (= L) is 60 cm, and the string is under a tension of 520 N.
What is the frequency of the fundamental and the first and second overtone?

 

[Parth Dave]

if 90 cm of the string is 3.6 g, how much does 60 cm weigh? Do you have any formulas that involve strings that may help you solve this?

You could try string theory.

Sorry, that won't happen again. I would just use a differential equation.
