A tuning fork resonates with a sonometer wire of length 1 m stretched with a tension of 6 N. When the tension in the wire is changed to 54 N, the same tuning fork produces 12 beats per second with it. The frequency of the tuning fork is $____$ Hz.

Answer:

Solution:

Sonometer: $f = (1/2 L) T / μ$ ; tension $6 \to 54 N$ (9 times) gives $f_{2} = 3 f_{1}$ .

The fork resonates at 6 N, so its frequency equals $f_{1}$ .

Beats: $f_{2} - f_{1} = 2 f_{1} = 12 \Rightarrow f_{1} = 6 Hz$ .
