1.	One end of a uniform glass capillary tube of radius r = 0.025 cm is immersed vertically in water to a depth h = 1 cm. The excess pressure in N/m^2 required to blow an air bubble out of the tube is : [Surface tension of water = 7 xx 10^(-2) Nm, Density of water = 10^3 kg m^(-3) , Acceleration due to gravity = 10ms^(-2)]
