Given information

Weight of tub + water= 100 N

Weight of brick= 50 N

Step-by-step explanation

Step 1.
  • Make a free-body diagram for the brick (mass m) and the water tub (mass w) (mass M). Because the water produces an upward buoyant force on the brick, Newton's third law states that the brick exerts an equivalent upward buoyant force.
  • On the water, there is a downward buoyant force. The normal force applied to the scale reading is a container of water. Then, applying Newton's second law, calculate for the normal force on the water using the equilibrium law water. Table 10–1 contains the densities.
