Q. No.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 \(0.03\)%. |

Poisson's ratio of a material is \(0.5.\) If the force is applied to a wire of this material, decrement in cross-sectional area of the wire is \(4\text{%}.\) The percentage increase in its length is:
1. \(1\text{%}\)
2. \(2\text{%}\)
3. \(2.5\text{%}\)
4. \(4\text{%}\)
1. \(1\text{%}\)
2. \(2\text{%}\)
3. \(2.5\text{%}\)
4. \(4\text{%}\)
