Question

Two tuning forks A and B when vibrated together, produce 4 beats per second. Frequency of A is
480 Hz. After B is filed and the two forks are again vibrated together, beat frequency is generated
again as 4 per second. What would be the original frequency of B? [Hint : Frequency of B should
increase after filing, so beat should increase as well after filing]
470 Hz
500 Hz
O 476 Hz
480 Hz
