The masses of the blocks are 2.0\text{ kg} and 5.0\text{ kg} and they can move freely along a straight horizontal track. The spring is compressed and the blocks are released simultaneously from rest. When the acceleration of the heavier block is 10\text{ m s}^{-2}, the acceleration of the lighter block will be

1. (A)5\text{ m s}^{-2}
2. (B)10\text{ m s}^{-2}
3. (C)20\text{ m s}^{-2}
4. (D)25\text{ m s}^{-2}

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