A steel wire of length im, mass 0.1kg and uniform cross sectional area `10^(-6) m^(2)` is rigidly fixed at both ends. The temperature of the wire is lowered by `20^(@)C`. If the transverse waves are set up plucking the string in the middle, calculate the frequency of the fundamental mode of vibration. `(Y=2xx10^(11)N//m^(2), a=1.21xx10^(-5)//^(@)C)`

Explanation

11 Hz
