A piano wire weighing 6 00 g and having a length of 90 0 cm emits a fundamental frequency corresponding to the “Middle C” ( ν = 261 63 Hz). Find the tension in the wire.

Question

Philoid · Accepted Answer

Mass density,

We know for fundamental frequency,

Putting the values, we get,

Now, given that,

So,

A piano wire weighing 600 g and having a length of 900 cm emits a fundamental frequency corresponding to the “Middle C” (ν = 26163 Hz). Find the tension in the wire.
