A stretched string of 1 m lengths and mass 5xx10^(-4) having tension of 20 N. if it is plucked at 25 cm from one end, then it will vibrate with frequency

A stretched string of length 1 m fixed at both ends , having a mass of 5 xx 10^(-4) kg is under a tension of 20 N . It is plucked at a point situated at 25 cm from one end . The stretched string would vibrate with a frequency of

The production manager of a company received the complaint that the quality of the goods was not good. After investigation, it come to light that the machines had become very old.
