Final answer:
The magnitude of the output force is 1 Newton (N).
Step-by-step explanation:
The magnitude of the output force can be calculated using the concept of mechanical advantage (MA) of a pulley system. In this case, there are 2 pulleys, so the MA is 2. The output force is the weight of the mass, which is 500 g or 0.5 kg. To find the magnitude of the output force, we multiply the weight of the mass by the MA of the pulley system.
Output force = Weight of the mass x MA
Output force = 0.5 kg x 2
Output force = 1 N
Therefore, the magnitude of the output force is 1 Newton (N).
