Option d) is the correct free body diagram.
Explanation:
A free-body diagram is a diagram that shows all the forces acting on a body. Each force is represented using an arrow, where:
- The length of the arrow is proportional to the magnitude of the force
- The direction of the arrow corresponds to the direction of the force
For the block in this problem, we have the following forces:
- The force F applied from the child, which acts at an angle with respect to the horizontal --> this rules out option a) and c), where the force acts horizontally
- The force of gravity (the weight of the object), labelled with W, which always acts downward --> this rules out option b), since the weight acts downward.
Therefore, the correct option is d).
(in reality, there should be another force: the normal reaction exerted by the floor on the block, N, acting upward).
