The frequency of a tuning fork A is 5% greater than that of a standard fork K. The frequency of another fork B is 3% less than that of K. When A and B are vibrated simulataneously 4 beats per second are heard. Find the frequencies of A and B.

Verified by Experts

Let the frequency of standard fork be K
`:.(105)/(100)K-(97)/(100)K=4` on solving `K=50 Hz`.
The frequency of `x=(105)/(100)xx50=52.2Hz`
Similarly frequency of `y=(987)/(100)xx50=48.5Hz`
