If two glass plates are quite nearer to each other in water, then there will be force of

Two thin glass plates are placed parallel to each other such that distance between them is very small. Each glass plate reflects 25% of incident energy and transmits remaining 75% Light beam is incident on this system. Consider the interference of two light beams obtained after one reflection from each glass plate. Calculate ratio of the maximum to minimum intensity.

Two pieces of glass plate one upon the other with a little water between them cannot be separated easily because of

Two large glass plates are placed vertically and parallel to each other inside a tank of water with separation between the plates equal to 1 mm. Find the rise of water in the space between the plates. Surface tension of water =0.075Nm^-1 .

A drop of water of volume V is pressed between the two glass plates so as to spread on area A. If T is the surface tension, the normal force required to separate the glass plates is :
