Homework Help: Physics

Posted by Tina on Wednesday, July 13, 2011 at 6:16pm.

A string with a linear density of 0.035 kg/m and a mass of 0.014 kg is clamped at both ends. Under what tension in the string will it have a fundamental frequency of 100 Hz?

The correct answer is 270N but I don't know how to get there.

Here are some of the equations we can use but if you know of others feel free to mention them.
T=1/f
f=1/T
v=(square root)F/(m/L)
Fn=nv/2L

Thanks for the help and please indicate which equation you chose if you end up picking one of the ones I have above.
