When two tuning forks A and B are sounded together x `beats//s` are heard. Frequency A is `n`. Now when one prong of B is loaded with a little wax, the number of beats/s decreases. The frequency of fork B is

When two tuning fork are sounded together produce x beats/s. The fequency of A is n_(A) . The fork B is loaded with little wax then x-1 number of beats per second are produced, then the frequency of fork B before loading will be

When two tuning forks A and B are sounded together, 4 beats per second are heard.The frequency of the fork B is 384 Hz. When one of the prongs of the fork A is filled and sounded with B, the beat frequency increases, then the frequency of the fork A is:

When two tuning forks were sounded together , 20 beats were produced in 10 seconds. On loading one of the fork with wax, the number of beats increases. If the frequency of unloaded fork is 512Hz , calculate the frequency of other.

When tuning forks A and B are sounded together 5 beats per second are heard. Frequency of A is 250Hz . On loading A with wax 2 beats per second are produced with B. The frequency of B is

When two tuning forks A and B are sounded together, 4 beats per second are head. The frequency of the fork B is 348 Hz. When one of the prongs of the fork A is filled and sounded with B, the beat frequency increases, then the frequency of the fork A is

When two tunning forks A and B are sounded together , 4 beats per second are heard . The frequency of the fork B is 384 Hz . When one of the prongs of the fork A is filled and sounded with B , the beat frequency increases , then the frequency of the fork A is

Two tuning forks A and B are sounded together and it results in beats with frequency of 4 beats per second . When A is loaded with wax, they again produces 4 beats per second . If frequency of A is 256 Hz, then the frequency of B is

When a tuning fork A and B are sounded together,the number of beats heard are 4 per second.When tuning fork A is field,the number of beats heard per second with B is changed to 3.If the frequency of tuning fork B is 384 Hz,the original frequency of A is

When a tuning fork A and B are sounded together,the number of beats heard are 4 per second.When tuning fork A is field,the number of beats heard per second with B is changed to 3.If the frequency of tuning fork B is 384 Hz,the original frequency of A is
