The following four wires are made of the same material. Which of these will have the largest extension when the same tension is applied ? L is the length and D is the diameter.

Of the following four wires of same material which will have maximum increase in length and which will have minimum increase in length if all are under the action of same force? Arrange the wires in the descending order of increase in length i) Natural length = 0.5m, diameter = 0.5mm ii) Natural length = 1m, diameter = 1mm iii) Natural length = 1.5m, diameter = 1.5mm iv) Natural length = 2.0m, diameter = 2mm
