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

A stretched string is in unison with a tuning fork of frequency 392Hz. If the length of the string is decreased by 2% , then the number of beats heard per second will be

The stirng stretched by tension T and length L vibrates in resonance with a tuning fork of frequency n. the tension in the stretched string is increased by 69% and length of string reduced by 35%. Then, the frequency of vibrating string is

A vibrating string produces 2 beats per secod when sounded with a turning fork of frequency 256Hz . Slightly increasing the tension in the string produces 3 beats per second. The initial frequency of the string may have been
