A force stretches wire X and gives it elastic potential energy $E$. The same force is then applied to wire Y, which is made of the same material and has the same starting length as wire X, but its diameter is twice that of wire X. Both wires follow Hooke’s law. What is the increase in elastic potential energy of wire Y?
- A$0.25E$
- B$0.5E$
- C$2E$
- D$4E$
