- Load $\times$ strain
- \(\frac{1}{2} \times\) load $\times$ strain
- Young's modulus $\times$ strain
- \(\frac{1}{4} \times\) load $\times$ extension
- \(\frac{1}{2} \times\) load $\times$ extension

The Correct Option is
Solution and Explanation
Concept:
Work done in stretching a wire equals area under force-extension graph.
Step 1: Graph relation.
Force increases linearly from 0 to final value.
Step 2: Work done.
\[ W = \frac{1}{2} \times \text{Force} \times \text{extension} \]
Step 1: Graph relation.
Force increases linearly from 0 to final value.
Step 2: Work done.
\[ W = \frac{1}{2} \times \text{Force} \times \text{extension} \]
