4. Two circular tubes are inserted vertically into a large container filled with liquid that has a surface tension of o = 0.07 N/m, and contact angle of 0 =10

deg. The density of the liquid is 960 kg/m³ the diameter of the first tube is 1.5 mm, and the diameter of the second tube is 2.5 mm. a) calculate how high will the liquid columns rise in each tube. b)Is this in conflict with Pascal's law? Explain.
