Question
If two glass plates have water between them and are separated by very small distance (see figure), it is verydifficult to pull them apart. It is because the water in between forms cylindrical surface on the side that givesrise to lower pressure in the water in comparison to atmosphere. If the radius of the cylindrical surface is R andsurface tension of water is T then the pressure in water between the plates is lower by :
