Question

Two containers without bottoms are placed on scales and filled with water to the same depth. One is tapered, to final area A while the other has constant area A along it's height (see figure). Thus the pressure at the bottom of the containers is the same and the bottoms both have the same surface area, but the two containers contain different volumes of water. Do the scales read the same values? If you say yes, explain how that can be since the containers have different amounts of water. If you say no, explain how that can be since the pressure at the bottom and the area of the base of the two containers are the same.

Explanation / Answer

no scale will not read same values because amount of water being more in A, will have more weight to be balanced so it will read more. now coming to pressure and area at bottom being same but in case of A there will conponent of force on walls of container in downwards direaction which will not be there in case B. so this means extra force is not due to liquid directly but by the edge of the wall of container B.
