The volume of the wood block is 100 cubic centimeter, and the density is 0.6 * 10 cubic meter. Q (1) when you press it into the water, what is the buoyancy of the wood block (2) How much pressure does the hand put on the block at this time?

Buoyancy f = 1 * 9.8 * 10 ^ (- 3) * 100 = 0.98n
F = buoyancy gravity = 0.98-0.6 * 10 ^ 3 * 100 * 10 ^ (- 6) = 0.92n
