A 70 cm long sonometer wire is in unison with a tuning fork. If the length of the wire is decreased by 1.0 cm, it produces 4 beats per second with the same tuning fork, find the frequency of the tuning fork.

A 75 cm long sonometer wire is in resonance with a tuning fork. If the length of the wire is decreased by 3 cm , it produces 6 beats per second with the tuning fork . What is the frequency of the tuning fork ?

A 75 cm long stretched string is tuned with a tuning fork. If the length of the string is reduced by 3 cm, it produces 6 beats with the tuning fork per second. Find out the frequency of the tuning fork.

A sonometer wire is in unison with a tuning fork. When the length of the wire is increased by 2% , the number of beats heard per second is 5, then the frequency of the fork will be

A stretched sonometer wire is in unison with a tuning fork. When the length of the wire is decreased by 1% 6 beats/s are heard, then the frequency of the tuning fork is

Two tuning forks when sounded together produce 5 beats per second. A sonometer wire of length 0.24 m is in unison with one of the forks. When the length of the wire is increased by 1 cm, it is unison with the other fork. Find the frequencies of the tuning forks.

A sonometer wire of length 65cm is in resonance with a tuning fork of frequency N. If the length of the wire is decreased by 1cm and it is vibrated with the same tuning fork, 8 beats/s are heard, then the frequency of the tuning fork will be

When the wire of a sonometer is 73 cm long, it is in resonance with a tuning fork. On shortening the wire by 0.5 cm, it makes 3 beats per second with the same fork. Calculate the frequency of the tuning 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 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 stretched sonometer wire is in unison with a tuning fork. When length of wire is increase by 1%, the number of beats heard per second is 5. then, the frequency of the fork is
