A vessel has a small hole at its bottom. If water can be poured into it upto a height of 7 cm without leakage `(g=10ms^(-2)`) the radius of the hole is (surface tension of water is `0.7Nm^(-1)`)

A small hollow sphere having a small hole in it is immersed in water to a depth of 50cm, before any water penetrates into it. Calculate the radius of the hole, if the surface tension of water is 7.2 xx 10^(-2) Nm^(-1) .

A long cylindrical vessel has a small hole of diameter D at its bottom. This vessel can be lowered vertically in water to a depth h without any water entering the vessel. Given : A=surface tension, B=density of liquid, C=acceleration due to gravity. The value of h is

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 , and accleration due to gravity, g=10 ms^-2 )

A small hollow sphere which has a small hole in it is immersed in water to a depth of 40 cm, before any water is penetrated into it. If the surface tensionof water si 0.073 Nm^(-1) , find the radius of the hole.
