Two vessels have the same base area but differnent shapes. The first vessel takes twice the vloume of water that the second vessel requires to fill up to a paricular common height . Is the force exerted by water on the base of the vessel the same in the two case? If so, why do the vessels filled with water to that same height give different reading on a weighting scale ?

Explanation

(i) As the two vessels have liquid to same height and the vessels have same base area, the force exerted = pressure `xx` base area will be same as pressure
=hpg.
(ii) Since the volume of water in vessel 1 is greater than in vessel (2) the weight of water = volume `xx` density `xx` h, so weight of first vessel will be greater than the water in second vessel.
