A note from a tuning fork is in unision with the note of a `25 cm` long stretched wire. If the length is changed to `25.5 cm` the tension remaining unchanged, 3 beats per second are heard. Find the frequency of the 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 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

A sonometer wire of certain length is stretched under a tension of 5 kgf and vibrates in unison with a tuning fork of unknown frequency. When the tension is changed to 4 kgf, it produces 5 beats per second with the tuning fork. Determine the frequency of tuning fork.

If a tuning produces 5 beat/s with a sonometer wire of lengths 40cm and 44cm , other factor remaining unchanged, then the frequency of the tuning fork will be

A sonometer wire is 31 cm long is in resonance with a turning fork of frequency n. If the length is increased by 1 cm and it is vibrated with the same tuning fork, then 8 beats/sec are heard. The frequency of the tuning fork is -

A wire under certain tension is in unison with a tuning fork when tension in the wire is increased by 2%, 3 beats/second are produced. Find the frequency of 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 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

A tuning fork produces 5 beats s^(-1) with a sonometer wire of length 78 cm. If the length of the wire iscreased byy 2 cm, then there is a resonance between the tuning fork and the wire. The frequency of the fork is
