When a few water drops placed between two glass plates, it is difficult to separate the glass plates? Why?

A water drop of 0.05 cm^(3) is squeezed between two glass plates and spreads into area of 40 cm^(2) . If the surface tension of water is 70 dyne cm^(-1) , then the normal force required to separate the glass plates from each other will be

Assertion : When there is a thin layer of water between two glass plates , there is a strong attraction between them . Reason : The pressure between the plate becomes less than atmospheric pressure because pressure inside a bubble or drop is greater than outside pressure.
