A solid glass rod of radius r = 1.3 cm is placed inside and coaxial with a glass cylinder of internal radius R = 1.7 cm. Their bottom ends are aligned and placed in contact with, and perpendicular to, the surface of an open tank of water (see Fig. 15-30). To what height will the water rise in the region between the rod and the cylinder? Assume that the angle of contact is 0° and use 72.8 mN/m for the surface tension of water.
