Two blocks are connected by a string as shown in the diagram. The upper block is hung by another string. A force applied on the upper string produces an acceleration of in the upward direction in both the blocks. If and be the tensions in the two parts of the string, then

The acceleration of the 500 g block in figure is

If in a stationary lift, a man is standing with a bucket full of water, having a hole at its bottom. The rate of flow of water through this hole is . If the lift starts to move up and down with same acceleration and then that rates of flow of water are and , then
