We have seen in class that water spontaneously rises up when put
in contact with a hydrophilic tube. A similar phenomenon occurs when water is put in contact with two parallel hydrophilic plates (Fig. 2). Given that the gap between the plates b = 100 µm, the width of the plates L = 20 cm, and the contact angle between the water and the plates is θ = 5 degrees, find the height of the capillary rise h.
