Question

a wooden cube of sides 10cm each has been dipped completely in water. calculate the up thrust of water acting on it.

Answer 1

Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is proportional to the weight of the fluid that the body displaces.

$F=\rho gV=1000\cdot9.8\cdot0.1^3=9.8(N)$
