A sphere of radius R is completely submerged in a container of water. The sphere displaces 1m^3 of water. What is the buoyant force? Assume the density of water ρw = 1000kg/m3 . Hint: The volume of a sphere is given by V = 4/3πR3 Then, find the density of the sphere given that its weight in air is 15, 000 kg · m/s2 and the radius R = 1m
