(96) A vessel is filled with two liquids of densities \( \rho_{1}=800 kg / m ^{3} \) and \( \rho_{2}=1000 kg / m ^{3} \) as shown in figure. The force that acts on the bottom of the vessel is (Neglect atmospheric pressure)
[Take \( g=10 m / s ^{2} \) ]
(1) \( 3.6 N \)
(2) \( 7.2 N \)
(3) \( 9 N \)
(4) \( 12.6 N \)
