Question

A string is stretched to a length of 337 cm and
both ends are fixed.
If the density of the string is 0.014 g/cm,
and its tension is 1750 N, what is the fundamental frequency?
Answer in units of Hz.

Answer 1

$$f=\frac{1}{2l}\sqrt{\frac{T}{\mu}}$$

$$f=\frac{1}{2(3.37)}\sqrt{\frac{1750}{0.0014}}=166\ Hz$$
