A body of mass 3.14 kg is suspended from one end of a non uniform wire of length 10m, such that the radius of the wire is changing uniformly from 9.8xx10^(-4) m at one end to 5xx10^(-4) m at the other end. Find the change in length of the wire in mm. Young's modulus of the material of the wire is 2xx10^(11)N//m^(2) (mass of wire is negligible)

A body of mass 3.14 kg is suspended from one end of a wire of length 10 m . The radius of cross-section of the wire is changing uniformly from 5xx10^(-4) m at the top (i.e. point of suspension) to 9.8xx10^(-4) m at the bottom . Young's modulus of elasticity is 2xx10^(11) N//m^(2) . The change in length of the wire is
