What are the sources of error in searlis experiment? How are the errors eliminated searlis experiment?

Explanation

### Step-by-Step Solution

1. **Identify the Sources of Error in Searle's Experiment:**
- **Yielding of the Wire:** When a load is applied to the lower end of the experimental wire, the wire may yield. This means that it can permanently deform under the stress, leading to inaccuracies in measurements.
- **Improper Adjustment of the Spirit Level:** If the air bubble in the spirit level is not properly adjusted, it can lead to incorrect readings of the angle or position of the wire, affecting the accuracy of the experiment.

2. **Methods to Eliminate or Minimize Errors:**
- **Use of Reference Wire:** To minimize the effect of yielding, a reference wire can be used alongside the experimental wire. This allows for a comparison between the two wires, ensuring that any yielding affects both wires equally, thus canceling out the error in measurements.
