Two wires of equal cross-section but one made of steel and the other of copper are joined end to end. When the cobination is kept under tension, the elongations in the two wires are found to be equal elongations in the two wire are found to be equal. What is the ratio of the lengths of the two wires? (Given, Young's modulus of steel = 2 xx 10^(11) Nm^(-2) and young's modulus of copper = 1.1 xx 10^(11) Nm^(-2) )

Two wires of equal cross section but one made of steel and the other of copper, are joined end to end. When the combination is kept under tension, the elongations in the two wires are found to be equal. Find the ratio of the lengths of the two wires. Young modulus of steel =2.0xx10^11Nm^-2 and that of copper =1.1xx10^1Nm^-2
