On a cello, the string with the largest linear density (1.58 10-2 kg/m) is the C string. This string produces a fundamental frequency of 65.4 Hz and has a length of 0.805 m between the two fixed ends. Find the tension in the string.

Explanation:

The relationship of between fundamental frequency, density of the string, length and tension of the string is:

where L/m is the linear density.
