Solution

There are two main action-reaction pairs acting on a person standing on the ground:

  1. Gravitational Force: The Earth pulls the person downwards (action), and the person pulls the Earth upwards (reaction). This is according to Newton's third law of motion which states that for every action, there is an equal and opposite reaction.

  2. Normal Force: The person pushes down on the ground due to their weight (action), and the ground pushes the person upwards with an equal force (reaction). This upward force is known as the normal force.

So, there are two action-reaction pairs acting on a person standing on the ground.
