Surface Tension The surface of a polar liquid, such as water, can be viewed as a series
Question:
(a) Show that the two slanted dipoles exert a net upward force on the dipole between them, and hence oppose the downward external force.
(b) Show that the dipoles attract each other and hence resist being separated. The force between dipoles opposes penetration of the liquid's surface and is a simple model for surface tension (see Section 143 and Fig. 14.15).
