A uniform rod of density ρ is placed in a wide tank containing a liquid of density ρ0 (ρ0>ρ) . The depth of liquid in the tank is half the length of the rod. The rod is in equilibrium, with its lower end resting on the bottom of the tank in this position the rod makes an angle θ with the horizontal.
