Question:
A capillary tube of radius $0.50 \mathrm{~mm}$ is dipped vertically in a pot of water. Find the difference between the pressure of the water in the tube $5.0 \mathrm{~cm}$ below the surface and the atmospheric pressure. Surface tension of water $=0.075 \mathrm{~N} / \mathrm{m}$.
Solution:
