Question

A wire of length l having tension t and radius r vibrates with fundamental frequency f

Answer 1

$\mathfrak{The\:Answer\:is}$


let the density of the material is ? so mass per unit length (µ) =??r^2 f=1/2L v(T/µ) =1/2L v(T/??r^2) now mass per unit length for second wire =??(2r)^2 =4??r^2 f' =1/4L v(2T/4??r^2) = f/2v2
