One end of an iron chain is fixed to a sphere of mass M = 10 kg and of diameter D = 0.3 m (the volume of such a sphere is `V = 0.0141 m^(3)`), while the other end is free. The length 1 of the chain is 3 m and its mass m is 9 kg. The sphere with the chain is in a reservoir whose depth `H = 3m`. Determine the depth at which the sphere will float, assuming that iron is 7.85 times heavier than water.
