1.	A vessel, whose bottom has round holes with diameter of 0.1 mm , is filled with water. The maximum height to which the water can be filled without leakage is (S.T. of water =75 dyne/cm , g=1000 cm/s)A. 100 cmB. 75 cmC. 60 cmD. 30 cm
Answer» Correct Answer - D Balancing axcess pressure we have `h rho g=(2S)/r` `implies h=(2S)/(r rho g)=(2xx75)/(0.005xx1xx1000)=30` cm
