When a wire subjected to a froce along its length, its length increases by `0.4%` and its radius decreases by `0.2%` then the Poisson's ratio of the material of the wire is

When a wire is subjected to a force along its length, its length increases by 0.4% andits radius decreaes by 0.2%. Then, the poisson's ratio of the material of the wire is

When the length of a wire is increased by 5%, its radius decreases by 1%. The Poission's ratio for the material of the wire is

When the length of a wire is increased by 5%, its radius decreases by 1%. The Poission's ratio for the material of the wire is

A wire is stretched such that its volume remains constant. The Poisson's ratio of the material of the wire is

A uniform metal wire has a length of 2m and diameter 2 cm. When it is stretched by 0.5 cm its diameter decrease by 0.015 mm. Then the Poisson's ratio for the metal of the wire is,

A wire is stretched such that its length increases by 0.2%. Its resistance

There is no change in the volume of a wire due to the change in its length on stretching. The Poisson's ratio of the material of the wire is
