The correct Answer is:
To determine how many wires are used in Searle's experiment for measuring Young's modulus of elasticity, we can follow these steps:
### Step-by-Step Solution:
1. **Understanding Searle's Experiment**: Searle's experiment is designed to measure the Young's modulus of elasticity of materials. It involves the use of wires under tension.
2. **Identifying the Components**: In this experiment, two wires are typically used. One wire is a standard wire with a known Young's modulus, while the other wire is the one for which we want to determine the Young's modulus.
3. **Application of Weight**: A weight is applied to the wires to create tension. The elongation of the wires is measured when the weight is applied.
4. **Calculating Young's Modulus**: Using the measurements of elongation and the known properties of the wires, the Young's modulus can be calculated.
5. **Conclusion**: Therefore, in Searle's experiment, **two wires** are used to determine the Young's modulus of elasticity.
### Final Answer:
**Two wires are used in Searle's experiment for determining Young's modulus of elasticity.**
