    Question

    A liquid is kept in a regular cylindrical vessel up to a

    certain height. If this vessel is replaced by another cylindrical vessel having half the area of cross-section of the bottom, the pressure on the bottom will
    A remain unaffected Correct Answer Incorrect Answer
    B be reduced to half the earlier pressure Correct Answer Incorrect Answer
    C be increased to twice the earlier pressure Correct Answer Incorrect Answer
    D be reduced to one-fourth the earlier pressure Correct Answer Incorrect Answer

    Solution

    Pressure exerted by the fluid column depends on height (h), density r and acceleration due to gravity (g). P = hrg i.e. independent of area of cross-section of the vessel.
