Two identical springs hang side by side (in parallel) and are connected to a load of 7.5\text{ N}. They each experience an extension of 2.5\text{ cm}. What is the force constant of ONE of the springs?

1. (A)1.5\text{ N m}^{-1}
2. (B)30\text{ N m}^{-1}
3. (C)150\text{ N m}^{-1}
4. (D)300\text{ N m}^{-1}

This question uses a figure or table from the paper — you'll see it when you practise.
