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.
Thanks for the help and please indicate which equation you chose if you end up picking one of the ones I have above.
lambda= 2*length= 2* mass/(massdenstiy)
= .028/(.035) meters=.8m
solve for tension F.
recheck my work to see if there is an error, I don't see it.
