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

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