Two similar wires under the same load yield elongation of `0.1 mm` and `0.05 mm` respectively. If the area of cross-section of the first wire is `4 mm^(2)`, then the area of cross-section of the second wire is

Two copper wires A and B of length l and 2l respectively, have the same area of cross-section. The ratio of the resistivity of wire A to the resistivity of wire B is

Two wires A and B are stretched by the same load. If the area of cross-section of wire 'A' is double that of 'B,' then the stress on 'B' is

Two wires A and B are stretched by the same load. If the area of cross-section of wire 'A' is double that of 'B,' then the stress on 'B' is

Two wires A and B are stretched by the same load . If the areas of cross - section of wire A is double that of B . then the stress in B is

A wire whose cross-sectional area is 2 mm^2 is stretched by 0.1 mm by a certain load, and if a similar wire of triple the area of cross-section is stretched by the same load, then the elongation of the second wire would be

When a load of 10 kg is hung from one end of a wire of length 5 m, the wire elongates by 5 mm. IF the young modulus for the material of the wire is 9.8 times 10^10 N.m^-2 , then find the area of cross section of the wire. [g=9.8 m.s^-2 ]

Two wires of the same length but of difference materials have diameter of 1mm and 3mm respectively.IF both of them are stretched by the same force,then the elongation of the first wire becomes thrice that of the second. Compare their Young's modull.
