A steel Can is floating on the surface of the water with some part submerged inside the water. If someone pushes the Can downward, which of the following will describe the reaction of the applied force?
The person will feel an upward force due to water.
If we apply force on the Can, the Can will feel the force downward from the person and the can, in turn, will push the water downward. By Newton’s third law, the water will apply an upward force on the Can and this force will be felt by the person, who is pushing the Can in the downward direction into the water.
