Length of a sonometer wire is either 95 cm or 100 cm. In both the cases a tuning fork produces 4 beats then the frequency of tuning fork is :-

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

A given length of sonometer wire is in resonance with a tuning fork. If the length of the wire is reduced by 4% the wire vibration with the fork produces 8 beats per second. The frequency of the tuning fork is

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 tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per sec . On loading the second tuning fork , sounded together with first tuning fork , produces one beat , then the frequency of the second tuning fork is

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 ?

2 wires of length 78 cm and 80 cm of a sonometer are kept at the same tension. A tuning fork produces 4 beats per second with each of them . Find out the frequency of the tuning fork .

A sonometer wire 64 cm long produces 8 beats per second with a tuning fork. If length of sonometer wire is increased by one centimeter it resonates with the tuning fork. The frequency of tuning fork is observed 64x . The value of x is

A tuning fork gives 4 beats with 50 cm length of a sonometer wire. If the length of the wire is shortened by 1 cm, the number of beats is still the same. The frequency of the fork is

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.
