A boy holds a box steadily in the air. Which picture correctly shows the forces applied to the box?
As an AI language model, I cannot directly display images. However, I can describe the correct picture for you.
When a boy holds a box steadily in the air, there are two main forces acting on the box:
1. The force of gravity, which pulls the box downward towards the ground.
2. The upward force applied by the boy's hand, often referred to as the "normal force."
The correct picture would depict the box being held by the boy's hand from underneath, applying an upward force. Additionally, gravity acts vertically downward, opposing the boy's hand and the normal force. This means the forces are in balance, indicating that the box is steady and not accelerating.
Overall, the picture should show an arrow pointing downward to represent gravity and an arrow pointing upward to represent the normal force applied by the boy's hand.
