37. (a) The downward force of gravity mg is balanced by the upward buoyant force of the liquid: mg = ρ g V s . Here m is the mass of the sphere, is the density of the liquid, and V s is the submerged volume. Thus m = V s . The submerged volume is half the total volume of the sphere, so () 3 1 2 43 s o Vr , where r o is the outer radius.
