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.
