Two vertical parallel glass plates are partially submerged in water. The distance between the plates is d and the length l. Assume that the water between the plates does not reach the upper edges of the plates and that the wetting is complete. Calculate the force of attraction between the plates. (ρ=density of water and σ= surface tension of water)
