Two wires `A` and `B` of the same dimensions are under loads of `4kg` and `5.5kg` respectively. The ratio of Young's moduili of the materials of the wire for the same elongation is

Two wires of same length and radius are joined end to end and loaded. The Young.s modulii of the materials of the two wires are Y_(1) and Y_(2) . If the combination behaves as a single wire them its Young.s modulus is

Two wires A and B of same dimensions are stretched by same amount of force .Young's modulus of A is twice that of B. Which wire will get more elongation?

Two wires A and B of same dimensions are stretched by same amount of force .Young's modulus of A is twice that of B. Which wire will get more elongation?

A load of 3kg produces an extension of 1.5 mm in a wire of length 3m and diameter 2mm . Young's modulus of the material of the wire is

Two wire of the same material and length stretched by the same force. If the ratio of the radii of the two wires is n : 1 then the ratio of their elongations is

A wire 3m long and diameter 0.3 mm is stretched by a load of 2kg. If the elongation is 2mm, find the Young.s modulus of the material of the wire and the potential energy stored in the wire.

The ratio of the length and diameters of two metallic wires A and B of the same material are 1:2 and 2 :1 respectively. IF both the wires are stretched by the same tension, then the ratio of the elongations of A and B will be
