Elasticity

A steel wire of length 3 m and a copper wire of length 2.2 m are connected end to end. When the combination is stretched by a force, the net elongation is 1.05 mm . If the area of cross-section of each wire is 6mm2, then the load applied is
(Young's moduli of steel and copper are respectively 2×1011Nm−2 and 1.1×1011Nm−2 )
