Question
A boy is carrying a bucket of water in one hand and piece of plastic in the other. After transferring the plastic piece to the bucket (in which it floats the boy will carry:
- same load as before
- more load as before
- less load as before
- either less or more load, depending on the density of plastic
The correct answer is: same load as before
The buoyant force exerted by water on the plastic piece will result in reaction one the bottom of the bucket to the same extent, thereby keeping the total load or weight to be the same as before.

A U-tube in which the cross-sectional area of the limb on the left is one quarter, the limb on the right contains mercury (density 13.6 g/cm3). The level of mercury in the narrow limb is at a distance of 36 cm from the upper end of the tube. What will be the rise in the level of mercury in the right limb if the left limb is filled to the top with water
