A guitar string has a mass per length of 2.33×10−3kg/m and a fundamental frequency of 146.8 Hz when it is under a tension of 82.4 N. The string breaks, and its owner has only a spare string of mass per length 6.80×10−3kg/m.

What tension should the 6.80×10−3kg/m string have so that its fundamental frequency is 146.8 Hz?
