    A uniformly tapering vessel is filled with a liquid of density \[900\,kg/{{m}^{3}}\]. The force that acts on the base of the vessel due to the liquid is \[(g=10\,m/{{s}^{2}})\]

    A)  3.6N                     

    B)                         7.2N     

    C)         9.0N                                     

    D)         14.4N

    Correct Answer: B

    Solution :

                    Pressure of liquid column \[=\text{ }h\rho g\] \[P=0.4\times 900\times 10\,N/{{m}^{2}}\] Force on the base \[=P\times area\]                 \[=P\times 2\times {{10}^{-3}}\,{{m}^{2}}\] \[=0.4\times 900\times 10\times 2\times {{10}^{-3}}N\]                 \[=7.2\,N\]
