The round stopper plugs the drain of a dish-washing sink filled with standing water. Determine the force F required to pull up the stopper, if the depth of the water is 225 mm. The density of standing water is p=1,020 kg/m' and the density of the metal stopper is p= 7,850 kg/m' for. Neglect the weight of the chain and that of the chain attachment to the stopper. The volume of a circular truncated cone is given by V =n(R* + Rr +r*)h, where R and rare the larger and smaller radii, respectively, of dhe circular arcas, and h is the height of the truncated cone.
