A fork and a monochord string 100 cm long give 4 beats per second.The string is made shorter without any change of tension untill it is in unsion the frok.If its length is now 99 cm, what is the frequency if the frok ?

A stretched sonometer wire gives 2 beats per second with a tuning frok when its length is 14.3 cm and also when its length is 14.5 cm.What is the frequency of the tuning frok ?

A tuning fork gives 15 beats per second when sounded with a sonometer wire of length 200 cm and 20 beats per second with that of length of 250 cm. calculate the frequency of the fork.

Two tuning forks A and B produce 5 beats per second when sounded together.A is in unsion with under a constant tension and B is in unison with the same wire of length 40.5 cm under same tension.Calculate the frequency of the forks

Two tuning forks when sounded together give 4 beats per second.if one of them is in unison with 96 cm length of a monochord under constant tension and the other with 97 cm length of the same string,find the frequencies of the fork.

Two tuning frok when sounded together give 4 beats per second.One is in unison with a length of 96 cm of a sonometer wire under a certain tension and the with 97 cm of the same wire under tension.Find the frequencies of the forks

A length of 34 cm of a sonometer wire gives 5 beats per second with a tuning fork.It again gives 5 beats per second when the length of the wire is increased to35 cm. What is the frequency of fork?

A tuning fork produces 10 beats per second with sonometer wire of length 95 cm and 100 cm . Find the frequency of the fork .

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?

A tuning fork vibrating with a sonometer having 20 cm wire produces 5 beats per second. The beat frequency does not change if the length of the wire is changed to 21 cm. The frequency of the tuning fork (in Hertz) must be
