Homework Help: Physics

Posted by James on Thursday, July 12, 2012 at 12:58am.

A string is 37.5 cm long and has a mass per unit length of 5.95 10-4 kg/m. What tension must be applied to the string so that it vibrates at the fundamental frequency of 612 Hz?

The answer is supposed to be 125 N, but I'm not sure how to get this answer. So far, I have found the mass of the string to be 2.0235 x 10e-04 kg. I'm not sure if this is useful or not, though. Any guidance is greatly appreciated.
