The net force of the scenario can be calculated by subtracting the gravitational force from the pulling forces applied by the workers. In this case, the pulling forces applied by the workers are 225 N each, and the gravitational force is 400 N in the opposite direction.
So, the net force is 225 N + 225 N - 400 N = 50 N.
Since the net force is positive (or 50 N), the slab of concrete will move upward.
Therefore, the correct response is:
50 N; the slab will move upward
