Asked by Nick
A guitar string, destined to be an upper E string, has length 100 cm and mass 0.400 g.
a. What is its mass per unit length?
u = m/L = 0.004 g/cm
b. What length of this string should be used on a guitar if the fundamental frequency is to be 330 Hz and its tension is to be 100 N?
I'm not sure which equations to use for part B.

Nick,
I'm working on this one myself. You can deduce from V = sqrt (T/M) where M=mass/length that f*2L = sqrt (T/M) but I keep getting the wrong answer for L. Unit conversion maybe?
