The volume of a stone is 20cm3, and its density is 3 * 10 cubic kg / m3. It is calculated by immersing it in water with a spring scale: (G is 10N / kg) (1) How much buoyancy does the stone bear? (2) What is the gravity of the stone? (3) When immersed in water, what is the indication of the spring scale?

solution
(1) F float = ρ water GV drain = =0.2N
(2) G = mg m = ρ V
So g = ρ V g = =0.6N
(3) F floating = G-F indication
F = G-F = =0.4N
