A tuning fork gives 4 beats per second with a sonometer wire under tension of 26 N. If the tension on the wire is decreased to 24 N the number of beats remains the same before. What is the frequency of the tuning fork?

A stretched sonometer wire is in unison with a tuning fork.When the length is increased by 4 % , the number of beats heard per second is 6. Find the frequency of the fork.

A tuning fork produces 4 beats//sec , with a sonometer wire of length 40 cm. It is found that when the length is increased to 44 cm, by keeping other factors constant, again 4 beat//sec are produced. What isthe frequency of the tuning fork?

Wire having tension 225 N produces six beats per second when it is tuned with a fork. When tension changes to 256 N, it is tuned with the same fork, the number of beats remain unchanged. The frequency of the fork will be

A sonometer wire under certain tension is in unison with a tuning fork. When only the tension in the wire is increased by 2 % , 3 beats per second are produces.Find the frequency of fork.

A sonometer wire is in unison with a tuning fork.When its lengths increases by 4%, it gives 8 beats per secon with the same the fork. The frequency of the fork is

A tuning fork C procues 8 beats per second with another tuning f+ork D of frequency 340 Hz . When the prongs of tuning fork C are filled a little, the number of beats produced per second decreases to 4 . Find the frequency of the tuning fork C before filing its prongs.

A sonometer wire 100 cm long produces a resonance with a tuning fork . When its length is decreased by 10 cm, 8 beats per second are heard. Find the frequency of tuning fork.

A tuning fork produces 8 beats per second with a tuning fork D of frequency 350 Hz .When the prongs of fork C are loaded with wax, the number of beats heard is 10 per second. Find the original frequency of fork C.

Nine tuning forks are arranged in order of increasing frequency . Each tuning fork produces 4 beats per second when sounded with either of its neighbours. If the frequency of the 9th tuning fork is twice that of the first, what is the frequency of the first tuning fork ?

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is
