The figure shows the effect of tube radius on the height to which capillary action can raise a fluid. 1.66 cm diameter 3.35 cm Capillary action depends on the radius of a tube. The smaller the tube, the greater the height reached. The height is negligible for large-radius tubes. (a) Calculate the height h (in m) for water in a glass tube with a radius of 0.830 cm-a rather large tube like the one on the left. (Assume the water is at 4.C.) (b) What is the radius ( in m) of the glass tube on the right if it raises the water to 3.35 cm
