Question

Newton's third law states that when an object exerts force on another object, the second object exerts an equal but opposite force on the first object. Which of the following shows an example of this

A. A girl hits a volleyball. Her hand exerts a force on the ball, and the ball exerts a force on her hand.

B. A woman presses on both sides of a box with equal force.

C. A moving cart becomes more difficult to stop as more mass is added to it.

Answer 1

A. A girl hits a volleyball. Her hand exerts a force on the ball, and the ball exerts a force on her hand.

Step-by-step explanation:

As rightly stated, from Newton's third law, we understand that for every action, there is an equal and opposite reaction, and if we closely examine the listed options, starting with A

A. The said girl acts by hitting the volleyball, i.e her hand exerts a force on the ball and the reaction occurs as the ball exerts a force on her hand.

B. Here, there is an action with no account of reaction, the woman presses the boxes (action), even thought with equal force on the sides, this option gives no detail of an equal and opposite reaction.

C. There is an action taking place by adding more masses to the moving cart, however, there is no explanation in this option for a reaction

Therefore, with a close look of the above listed options, it can be concluded that only option A shows an example of Newton's third law.
