On the physical problems of Archimedes principle There is a metal ball hanging at the lower end of the spring dynamometer. The indication of the spring dynamometer is 10N. If half of the metal ball is immersed in water, the indication of the spring dynamometer is 8N. If the metal ball is completely immersed in water, what is the indication of the spring dynamometer?

It is known that g = 10N, f = 10n-8n = 2n, g = 9.8n/kg, ρ water = 1.0 * 10 cubic kg / M & sup3;
Find: F 2
1 / 2V discharge = f floating 1 / ρ water G
So V row = 4.08 * 10 of the sub fourth power
F floating 2 = ρ water GV drainage = 3.9984n
