Question
Two vessels A and B of different shapes have the same base area and are filled with water up to the same height h (see figure). The force exerted by water on the base is FA for vessel A and FB for vessel B. The respective weights of the water filled in vessels are WA and WB. Then
Options
A.FA > FB ; WA > WB
B.FA = FB ; WA > WB
C.FA = FB ; WA < WB
D.FA > FB ; WA = WB
Solution
WA > WB as mass of water in A is more than in B
PA = PB
Area of A = Area of B
or PA AreaA = PB AreaB
or FA = FB .
PA = PB
Area of A = Area of B
or PA AreaA = PB AreaB
or FA = FB .
