In an experiment of standing waves, a string 90 cm long is attached to the prong of an electrically driven tuning fork that scillates perpendicular to the length of the string at a frequency of 60 Hz . The mass of the string is 0.044 kg . What tension (in newton) must the string be under (weights are attached to the other end) if it is to oscillate in four loops?

A body of mass 2 kg is tied to the end od a string 2 m long and revolved in horizontal circle .If the breaking tension of the string is 400 N, then the maximum velocity of the body will be

A body of mass 2 kg is tied to the end of a string 2 m long and revolved in horizontal circle. If the breaking tension of the string is 400 N, then the maximum velocity of the body will be

A vibrating string of certain length l under a tension T resonates with a maode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also gereates 4 beats per second when excited along with a tuning fork of frequency n . now when the tension of the string is slightly increased the number of beats reduces 2 per second. assuming the velocity of sound in air ti be 340 m//s , the frequency n of the tuning fork in Hz is
