Question

Two tuning forks A and B produce 4 beats per second. On loading B with wax 6 beats are produced. If the quantity of wax is reduced the number of beats drops to 4. If the ency of D. frequency of A is 326 Hz, find the frequency of B.​

Answer 1

Answer: Possible frequencies of B are 256±4=260or252. As some wax continues to be attached finally and number of beats / sec =4, therefore, final frequency must be less than the initial frequency. Hency initial freq. of B=260Hz
