young's module of two wires x and y are in the ratio 25:16 wire x is 4m long and has radius R wire y is 9m long and has radius 2mm .If the two wires stretch by the same length for a given load,then the value of R is

Young’s moduli of two wires A and B are in the ratio 7 : 4. Wire A is 2 m long and has radius R. Wire B is 1.5 m long and has radius 2 mm. If the two wires stretch by the same length for a given load, then the value of R is close to:

Two wires A and B are made of same material. The wire A has a length l and diameter r while the wire B has a length l and diameter r while the wire B has a length 2l and diameter r/2. If the two wires are stretched by the same force the elongationn in A divided by the elongation in B is

Two metallic wires A and B are connected in parallel. Wire A has length l and radius r, wire B has a length 2 l and radius 2r. Compute the ratio of the total resistance of parallel combination and the resistance of wire A.

Two steel wires of the same radius have their lengths in the ratio of 1:2 . If they are stretched by the same force, then the strains produced in the two wires will be in the ratio of

Two wires A and B have equal lengths and aremade of the same material , but diameter of wire A is twice that of wire B . Then, for a given load,

Two wires of copper are given . Write A: length e and radius r, wire B: length e and radius 2r. If Young's modulus for wire A is Y_(A) and for wire B is Y_(B) . Then-

The extension of a wire by the application of a load is 2 mm. The extension in a wire of the same material and same length but half the radius by the same load is
