(4) Consider a drop of liquid on a surface as shown in the figure. Note that the contact angle is less than pi/2. / / / / / / / (a) Find an expression for the maximum height of this drop given the surface tension and contact angle. Use unit analysis to check your answer. (b) If the liquid is Methylene iodide (density 3.32 g/cm³) on soda-lime glass (contact angle 29°), find the maximum height.
