Two similar sonometer wires given fundamental frequencies of 500 Hz. These have same tensions. By what amount the tension be increased in one wire so that the two wires produce 5 beats/sec:

Options:

Answer:

Solution:

The other frequency is 505 Hz. $f \propto T$ , so $T_{2} / T_{1} = 1.01^{2} = 1.0201$ , an increase of about 2%.
