Two very wide parallel glass plates are held vertically at a small separation d, and dipped in water. Some water climbs up in the gap between the plate. Let S be the surface tension of water P_(0)= atmospheric pressure, P= pressure of water just below the water surface in the region between the plates-

A soap bubble, having radius of 1mm, is blown from a detergent solution having a surface tension of 2.5 xx 10^(-2)N//m . The pressure inside the bubble equals at a point Z_(0) below the free surface of water in a container. Taking g= 10 m//s^(2) , density of water =10^(3)kg//m^(3) , the value of Z_(0) is

If two 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 ot 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 lowr by:
