In which case there is maximum extension in the wire, if same force is applied on each wire

In which case there is maximum tension in the wire, if same force is applied on each wire

A force F is applied on the wire of radius r and length L and change in the length of wire is l . If the same force F is applied on the wire of the same material and radius 2r and length 2L. Then the change in length of the other wire is

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.

Two wires of same diameter of the same material having the length l and 2l If the force F is applied on each, the ratio of the work done in two wires will be
