Question

A fish is swimming in the ocean. Which of the following represents the interaction between the fish and the water?

• A. The force of the fish points back while the force of the water points forward
• B. The force of the fish must be greater than the force of the water for the fish to move
• C. The force of the fish must be less than the force of the water for the fish to move
• D. The forces point in the same direction in liquid media such as the ocean
• E. Newton's third law does not apply in water

Answer 1

The correct option is A The force of the fish points back while the force of the water points forward

The forces on the fish and water forms an action-reaction pair.

The force on the fish by water is in forward direction as a reaction to the force on water by fish in backward direction.

This force on fish makes it move in the forward direction.
