To determine which picture correctly shows the forces applied to the box held steady in the air, we should consider the concepts of force and equilibrium.
When the boy holds the box steadily in the air, there are two main forces acting on the box:
- The gravitational force (weight) acting downward, due to the mass of the box.
- The upward force exerted by the boy’s hand holding the box, which is equal in magnitude and opposite in direction to the gravitational force, allowing the box to remain stationary.
Since the box is held steadily and not moving, these two forces must be equal in magnitude and opposite in direction, resulting in a net force of zero.
Without the images, I cannot identify which one is correct. However, you should look for an option that shows:
- An arrow pointing down (representing the weight) that has the same length as
- An arrow pointing up (representing the force from the boy) to indicate balance (equal forces).
Choose the option that accurately illustrates these two forces as equal and opposite.
