**Problem Description:**

Three blocks are connected by light ropes as shown in the diagram. There is no friction in this problem (from the table or the pulleys). The mass of the middle block (resting on the table) is 0.231 kg. Note that there are two separate/independent ropes, one on the left and one on the right of the middle block.

**Diagram Explanation:**

- The diagram depicts a horizontal table with a block of 0.231 kg resting on it.
- On the left side, a 4.00 kg block is suspended, connected over a pulley by a rope to the middle block.
- On the right side, a 2.00 kg block is suspended, connected over another pulley by a rope to the middle block.
- Both ropes are separate and independent.

**Questions:**

1. In which direction will the middle block accelerate?
2. Find the magnitude of the acceleration of the middle block. (Hint: Write down 3 equations, one for each block. Are the magnitudes of their accelerations the same?)
