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?

240.59 N

Explanation:

We are given that

Mass per unit length=m/l=

Fundamental frequency,f=146.8 Hz

Tension=T=82.4 N

Mass per unit length=

We have to find the tension.

Velocity,v=

New tension,T'=

Hence, the string  should have tension 240.59 N  so that its fundamental frequency is 146.8 Hz

i think if it were me i whould divide 300 dide 15
