Find the stress to be applied to a steel wire to stretch it by 0.025% of its original length. Y for steel is 9xx10^(10) Nm^(-2)

The radii and Young's moduli of two uniform wires A and B are in the ratio 2:1 and 1:2 respectively. Both wires are subjected to the same longitudinal force. If the increase in length of the wire A is one percent, the percentage increase in length of the wire B is
