A glass capillary tube with a radius of 0.050 mm is inserted into an open container filled with an unknown liquid, and the meniscus has an appearance similar to Figure 10.35A. It is found that the surface tension causes the liquid in the tube to rise a distance of 2.5 cm relative to the surface of the liquid outside the tube. If the density of the liquid is what is the surface tension?

(reference figure 10.35A)
