Two tuning forks A and B produce 4 beats `//`sec. On loading B with wax, 6 beats `//` sec are heard. If quantity of wax is reduced, the number of beats per second again becomes 4.Find the frequency of B if the frequency of A is 256 Hz.

Two tunig forks A and B produce 6 beats // sec. On loading A with wax number of beats remains unaltered. However, when a little of wax is removed, the number of beats becomes 2 in 2 seconds. Calculate original frequency of A if that of B is 256.

A tuning fork A of frequency 256 Hz when sounded with tuning fork B of unknown frequency produces 4 beats/s. When B is loaded with wax, 6 beats/s were heard. If some of the wax is reduced, the number of beats again reduces to 4 beats/s. Determine the initial frequency of B.

If two tuning forks A & B give 4 beats/sec. with each other, on loading A with wax , 2 beats/sec. are given. If frequency of A is 256 Hz, then frequency of B is-

Two tuning forks A and B produced 10 beats per second when sounded together. On slightly loading fork A with a little wax, it was observed that 15 beats are heard per second. If the frequency of fork B is 480 Hz, then the frequency of A before it was loaded would be

Two tuning forks A and B vibrating simultaneously produce 5 beats//s . Frequency of B is 512 Hz . If one arm of A is filed, the number of beats per second increases. Frequency of A is

When a tuning fork A of frequency 100 Hz is sounded with a tuning fork B , the number of beats per second is 2 . On putting some wax on the prongs of B , the number of beats per second becomes 1 . The frequency of the fork B 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 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

Two tuning forks A and B produce 8 beats per second when sounded together ,When B is slightly loaded with wax the beats are reduced to 4 per second .If the frequency of A is 512 Hz,the frequency of B is

Two tuning forks A and B give 4 beats/s when sounded together. If the fork B is loaded with wax 6 beats/s are heard. If the frequency of fork A is 320 Hz, then the natural frequency of the tuning fork B will be
