Choose the correct option for each question. There is only one correct response for each question.
Which instrument can be used to measure force?

Options

A. Spring balance
B. Metre scale
C. Calorimeter
D. Barometer

Answer

To solve the question of which instrument can be used to measure force, we will analyze each of the provided options step by step.

### Step 1: Analyze the Options
We have four options to consider:
1. Spring Balance
2. Meter Scale
3. Calorimeter
4. Barometer

### Step 2: Evaluate Each Option
- **Spring Balance**: This instrument measures force by the extension of a spring. It is commonly used to measure weight, which is a force due to gravity acting on an object. Therefore, it is a suitable instrument for measuring force.

- **Meter Scale**: This is a measuring tool used to measure lengths or distances. It does not measure force, so it is not the correct option.

- **Calorimeter**: This device is used to measure the heat transfer in physical and chemical processes. It does not measure force, making it an incorrect choice.

- **Barometer**: This instrument measures atmospheric pressure. It does not measure force directly, so it is not the correct answer.

### Step 3: Conclusion
After evaluating all the options, the only instrument that can be used to measure force is the **Spring Balance**.

### Final Answer
The correct option is **Spring Balance**.
