Transcribed Image Text:### Problem Description
The diagram shows two 50 N weights connected to opposite sides of a scale using ropes that pass over pulleys. The question asks: What will the scale read?
### Diagram Explanation
- **Setup**: The figure includes a central scale with two pulleys, each on opposite sides. Two weights, each labeled 50 N, are suspended from the ends of ropes that run over the pulleys and attach to the scale.
- **Forces**: Both weights exert a force of 50 N due to gravity.
### Question Options
1. 200 N
2. 25 N
3. 50 N
4. 0 N
5. 100 N
### Explanation
Considering the equilibrium in the system and how scales measure tension:
- The forces exerted by the weights are equal and opposite, causing tension in the rope connected to each side. The total downward force is 100 N (50 N from each weight).
- The scale measures the tension in the system; thus, it will read the combined effect of both weights, which sums to 100 N.
Therefore, the correct answer is 100 N.
