Four spring-loaded toy launchers contain compression springs P, Q, R and S. The table gives the force on each spring when it is fully compressed.
Each spring is below its limit of proportionality and is not inelastically deformed.
| Spring | Force in N | Spring constant in N/m |
|---|---|---|
| P | 24 | 600 |
| Q | 18 | 180 |
| R | 16 | 800 |
| S | 10 | 100 |
Which spring has the greatest elastic potential energy store when fully compressed?
spring R
spring Q
spring P
spring S
