Two wires are made of the same material and have the same volume. However wire 1 has cross-sectional area A and wire 2 has cross-sectional area 3A. If the length of wire 1 increases by Deltax on applying force F, how much force is needed to stretch wire 2 by the same amount?

Choose correct alternative. Two wires of same material and same length are connected in series. The area of cross section of wires is in ratio 3:1 . The resistance of thicker wire is 10 Omega . The total resistance of combination is

Assertion : Two wires A and B have the same cross-sectional area and are made of the same material but the length of wire A is twice that of B. For a given load, the strain in wire A is twice that in B. Reason : For a given load, the extension in a wire is prportional to its length.

P and Q are two wires of same length and different cross sectional areas and made of same material. Name the property which is same for both the wires.
