A glass capillary tube of internal radius `r=0.25 mm` is immersed in water. The top end of the tube projects by `2 cm` above the surface of water. At what angle does the liquid meet the tube? Surface tension of water `=0.7Nm^(-1)`.

A capillary tube of radius 0.50 mm is dipped vertically in a pot of water. Find the difference between the pressure of the water in the tube 5.0 cm below the surface and the atmospheric pressure. Surface tension of water =0.075Nm^-1
