A piece of wood with a mass of 1kg and a density of 0.6 × 103kg / m3 floats on the water surface. How much buoyancy does the object bear? What is the volume of the immersed part?

A piece of wood with a mass of 1kg and a density of 0.6 × 103kg / m3 floats on the water surface. How much buoyancy does the object bear? What is the volume of the immersed part?

M = 1kg, take g = 10. Buoyancy = block weight = 10N
The volume of the immersed part is the volume of the boiled water, that is, the weight of the water is equal to the weight of the wood block
V=10/10~3=0.01m3
