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

Two tuning fork A and B are sounded together gives 5 beats per second. If frequency of B is 260 Hz and after loading B with was the beat frequency increases the frequency of A 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 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

Two tuning forks A and B give 4 beats per second. The frequency of A is 256 Hz . On loading B slightly, we get 5 beats in 2 seconds. The frequency of B after loading 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

If two tuning fork A and B are sounded together they produce 4 beats per second. A is then slightly loaded with wax, they produce 2 beats when sounded again. The frequency of A is 256. The frequency of B will be

On sounding two tuning forks A and B together 5 beats per second are produced. On filling A slightly, the number of beats per second becomes 2. If the frequency of the A is 384 Hz. Then the frequency of B will be -

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 of unknown frequency is sounded with another tuning fork B of frequency 256Hz, then 3 beats per second are observed. After that A is loaded with wax and sounded, the again 3 beats per second are observed. The frequency of the tuning fork A is

Two tuning forks when sounded together produce 5 beats per second. The frequency of one of them is 250 Hz. When the other fork is slightly loaded, they produce 7 beats/s. Then the frequency of other tuning fork without loading is
