This question deals with the physics of resonance and sound. The possible frequency of the pano key is 258hz.

How to compute the variation in frequency

The beat of a frequency is the difference (an absolute value) in the frequencies produced by the two waves.

Beat per second equals |f1 - f2| Where

ft = Frequency of the Tunning fork and

fp= Frequency of the Piano Key

Hence

3 =  261 - fp

Solving for fp,

fp = 261-3

= 258hz
