Hydrostatics: Stevin's Theorem

Very Hard

(Originais Teachy 2023) - Question Very Hard of Physics

A wooden block with a density of 600 kg/m^3 and a volume of 0.02 m^3 is submerged in a container containing water, which has a density of 1000 kg/m^3. The wooden block is connected by a wire to a scale resting at the bottom of the container. The wire exerts a force that is transmitted to the scale. Considering the acceleration due to gravity as g = 10 m/s^2, calculate the reading on the scale. Assume that the scale is calibrated to measure the force correctly and that there are no currents inside the container that could affect the scale reading. Explain how the scale reading is related to the Stevin's Theorem and the pressure exerted by the wooden block on the water.
