A steel wire and copper wire of the same diameter and of length 1m and 2m respectively are connected end to end and a force is applied. The increase in length of the combination is 0.01m.Calculate the elongation produced in the individual wires. Given that Y of copper is 12 x 10^(10) Nm^(2) and that of steel is 20 x 10^(10) N m^(-2).
