    A uniformly tapering vessel is filled with a liquid of density 900 kg / m3. The force that acts on the base of the vessel due to the liquid is : \[(g=10\,m/{{s}^{2}})\]

    A)  3.6 N                                    

    B)  7.2 N

    C)  9.0 N                                    

    D)  14.4 N

    Correct Answer: B

    Solution :

                     Pressure of liquid column \[=h\rho g\]                 \[p=0.4\times 900\times 10\,N/{{m}^{2}}\] 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
