Question

A solid cube is submerged in a container of water of density p,. The cube has mass M, volume Vc, and density ½pw. The water exerts an upward buoyant force on the cube of magnitude PwVcg. Which of the diagrams is the best representation of the forces exerted by the water on the cube?

Answer 1

Explanation:

We have that the density of the cube is less than the density of water.

Which means that naturally the cube will float, so if it is immersed in water, the upward force will be greater than the downward push.

The diagram that represents a greater force upwards than downwards is the diagram for option C, so the correct option is option C.
