## Question

### Solution

Correct option is

5000 J

Side of the cube l = 1 m. Base area of the cubical vessel = l2. Mass of water contained in a height . Weight of this water . Therefore, work done in pumping out water up to a height x is

Therefore, total work done in pumping out water up to a height l is

= 5000 J
