A tuning fork produces 7 beats/s with a tuning fork of frequency 248Hz. Unknown fork is now loaded and 7 beats/s are still heard. The frequency of unknown fork was

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 under certain tension is in unison with a tuning fork. When only the tension in the wire is increased by 2 % , 3 beats per second are produces.Find the frequency of fork.

A string under a tension of 129.6 N produces 10 beats per sec when it is vibrated along with a tuning fork. When the tension in the string is increased to 160 N, it sounds in unison with the same tuning fork, Calculate the fundamental frequency of the tuning fork.
