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

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

A thin liquid film of thickness 5 xx 10^(-5) m is formed between two glass plates of surface area 1 xx 10^(-2) m^(2) , If the surface tension of the liquid is 60 xx 10^(-2) n/m the force that is required to separate the glass plates is

If a water drop is kept between two glass plates, then its shape is

A drop of water of volume 0.05 cm^(3) is pressed between two glass plates, as a consequence of which, it spreads and occupies an are of 40 cm^(2) . If the surface tension of water is 70 "dyne"//cm , find the normal force required to separate out the two glass plates is newton.

A drop of water volume 0.05 cm^(3) is pressed between two glass -paltes, as a consequence of which, it spreads and occupies an area of 40 cm^(2) . If the surface tension of water is 70 dyn e//cm , find the normal force requried to separte out the two glass plates in newton.

A drop of liquid pressed between two glass plates spreads to a circle of diameter 10 cm. Thickness of the liquid film is 0.5 mm and surface tension is 70xx10^(-3)Nm^(-1) the force required to pull them apart is

A small drop of water of surface tension S is squeezed between two clean glass plates so that a thin layar of thickness d and area A is formed between them. If the angle of contact is zero, what is the force required to pull the plates apart?

A drop of water of mass m and density rho is placed between two weill cleaned glass plates, the distance between which is d . What is the force of attraction between the plates? (T= surface tension)

Two glass plates are separated by water. If surface tension of water is 75 dyn//cm and the area of each plate wetted by water is 8 cm^(2) and the distance between the plates is 0.12 mm , then the force applied to separate the two plates is
