A copper wire of length 3 m and area of cross-section `1mm^(2)` passes through an arrangement of two friction-less pulleys `P_(1)` and `P_(2)`. One end of the wire is rigidly clamped and a mass of 1 kg is hanged from the other end if the young's modulus for copper is `10xx10^(10)N//m^(2)` , then the elongation in the wire is

A copper wire of length 1.0 m and a steel wire of length 0.5 m having equal cross-sectional areas are joined end to end. The composite wire is stretched by a certain load which stretches the copper wire by 1 mm. If the Young’s modulii of copper and steel are respectively 1.0xx10^(11)Nm^(-2)"and"2.0xx10^(11)Nm^(-2), the total extension of the composite wire is:
