A long cylindrical glass vessel has a pinhole of diameter $0.2\, mm$ at its bottom. The depth to which the vessel can be lowered vertically in a deep water bath without the water entering into the vessel is (surface tension of water, $T=0.07 \,Nm ^{-1}$, acceleration due to gravity, $g=10 \,ms ^{-2}$ )
