Two wires A and B of same cross-section are connected end to end. When same tension is created in both wires, the elongation in B wire is twice the elongation in A wire. If LA and LB are the initial lengths of the wires A and B respectively, then (Young's modulus of material of wire A=2×1011Nm−2 and Young's modulus of material of wire B=1.1×1011Nm−2 ).
