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 on applying force F. How much force is needed to stretch wire 2 by same amount.

The dimensions of four wires of the same material are given below, in which wire the increase in length will be maximum when the same strain is applied.

A wire is loaded by 6 kg at its one end, the increase in length is 12 mm. If the radius of the wire is doubled and all other magnitudes are unchanged, then increase in length will be.............

There are two wires of same material and same length. While the diameter of second wire is 2 times, the diameter of first wire. Then what will be the ratio of extension produced in the wire by applying same load ?

When the length of a wire having cross-section area 10^–6 m² is stretched by 0.1% then tension in it is 100 N. Young's modulus of material of wire is...........

Two wires of equal lengths are made of the same material wire A has a diameter that is twice as that of wire B. If identical weights are suspended from the ends of these wires the increase in length is............
