A vertical spring stretches by $0.05\text{ m}$ under a load of $10\text{ N}$. When a second identical spring is connected in series (end-to-end) with the first spring and supporting the same $10\text{ N}$ load, what is the total elastic potential energy stored in the two-spring system?

• A$0.25\text{ J}$
• B$0.50\text{ J}$
• C$1.00\text{ J}$
• D$2.00\text{ J}$
