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 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 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 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.

In resonance tube, an air column of length 32 cm is in unison with a tuning fork.If the length is changed to 32.4 cm, 5 beats per second are heard. Find the frequency of the tuning fork.

A sonometer wire resonates with a tuning fork. It itslength isincreased by 5%,10 beats are produced per second. The frequency of the tuning fork is.

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?

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
