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

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

The wire is stretched to increase the length by 1%. Find the percentage change in the resistance.

A wire has Poisson's ratio 0.3 . If the change in the length of the wire on stretching it is 1% then percentage change in the volume of the wire will be

A piece of copper wire has twice the radius of a piece of steel wire. Young's modulus for steel is twice that of the copper. One end of the copper wire is joined to one end of the steel wire so that both can be subjected to the same longitudinal force. By what fraction of its length will the steel have stretched when the length of the copper has increased by 1% ?
