A tuning fork of unknown frequency vibrates in unison with a wire of certain stretched under a tension of 5 kg f. It produces 6 beats per second with the same wire, when tension is changed to 4.5 kg f. Find the frequency of tuning fork.

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.

A tuning fork produces 6 beats/sec with sonometer wire when its tensions are either 169N or 196N . The frequency of that fork is

A tuning fork when vibrating along with a sonometer produces 6 beats per second when the length of the wire is either 20 cm or 21 cm . Find the frequency of the tuning fork.

A tuning fork produces 4 beats/s with a sonometer wire when its lengths are 50cm , 51cm . The frequency of that tuning fork is

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 somometer wire produces 2 beats per second with a tuning fork, when the length of the wire is either 102cm or 104 cm . The frequency of the tuning fork is
