Two identical springs are arranged in parallel. As shown, a weight of $8.0\,\text{N}$ is suspended from the pair. The graph gives the change in force with length for one of the springs. What is the strain energy stored in one of the springs?
- A$0.060\,\text{J}$
- B$0.12\,\text{J}$
- C$0.14\,\text{J}$
- D$0.24\,\text{J}$
