1 2 glass plates have water between them and are separated by very small distance see figure it is very difficult to pull them apart It is because the water in between forms cylindrical surface on the side that gives rise to lower pressure in the water in comparison to atmosphere If the radius of the cylindrical surface is R and surface tension of water is T then the pressure in water between the plates is lower by 3 T 4R T 2R 4T R 2T E Cylindrical surface of water
