A wood- sphere of radius 10 cm has a core of lead, also in the shape of a sphere. the wood sphere, when placed in water, floats with only 10% of its volume above the water line.
the density of water is 1000 kg/m^3 wood is 676kg/m density of lead is 11,340....
what is the magnitude of buoyancy force ?
what is the total mass of sphere?
what is the mass of wood and lead portions ?
what is the radius of lead core?
