The increase in the length of a wire on stretching is \(0.04\)%. If Poisson's ratio for the material of wire is \(0.5,\) then the diameter of the wire will:

1. decrease by \(0.02\)%. 2. decrease by \(0.01\)%.
3. decrease by \(0.04\)%. 4. increase by \(0.03\)%.

The Poisson's ratio of a material is \(0.4.\) If a force is applied to a wire of this material, there is a decrease in the cross-section area by \(2\)%. In such a case the percentage increase in its length will be:

1. \(3\)% 2. \(2.5\)%
3. \(1\)% 4. \(0.5\)%
