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 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 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

In the Young's experiment. It length of wire and radius both are doubled then the value of Y will become

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

The ratio of the lengths of the two wires of same Young's modulus and same diameter is 5:3 . They are stretched by the same force. Then the ratio of the work done on the two wires to stretch is
