Question

The vessel shown in the figure has two sections of areas of cross–section A subscript 1 end subscript and A subscript 2 end subscript . A liquid of density rho fills both the sections, up to a height h in each. Neglect atmospheric pressure:-

  1. The pressure at the base of the vessel is 2 h rho g    
  2. The force exerted by the liquid on the base of the vessel is 2 h rho g A subscript 2 end subscript    
  3. The weight of the liquid is less than 2 h rho g A subscript 2 end subscript    
  4. The walls of the vessel at the level X exert a downward force h rho g open parentheses A subscript 2 end subscript minus A subscript 1 end subscript close parentheses on the liquid    

The correct answer is: The force exerted by the liquid on the base of the vessel is 2 h rho g A subscript 2 end subscript
