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 [

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 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

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

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 forks A and B produce 6 beats per second. Frequency of A is 300 H_(Z) . When B is slightly loaded with wax, beat frequency decreases . Find original frequency of B .
