3. With what force are two vertical and parallel glass plates, partially submerged in water, attracted if the distance between them is 1 mm? The width of the plates is 15 cm, the surface tension of water is 71.96 mJ / m2, the contact angle is 0 °. The height of the plates is such that the rising water does not reach their upper edges. Take the density of water equal to 0.997 g / cm3.
