A liquid having surface tension T and density ρ is in contact with a vertical solid wall. The liquid surface gets curved as shown in the figure. At the bottom the liquid surface is flat. The atmospheric pressure is Po . (i) Find the pressure in the liquid at the top of the meniscus (i.e. at A) (ii) Calculate the difference in height (h) between the bottom and top of the meniscus.

A glass prism has its principal section in form of an equilateral triangle of side length l . The length of the prism is L (see fig.). The prism, with its base horizontal, is supported by a vertical spring of force constant k. Half the slant surface of the prism is submerged in water. Surface tension of water is T and contact angle between water and glass is 0∘ . Density of glass is d and that of water is ρ(<d) . Calculate the extension in the spring in this position of equilibrium.
