Two identical springs of copper and steel are equally strectched. On which more work will have to be done?

Explanation

To determine which of the two identical springs (one made of copper and the other made of steel) requires more work to stretch equally, we can follow these steps:

### Step 1: Understand the Work Done on Springs
The work done \( W \) to stretch a spring is given by the formula:
\[ W = \frac{1}{2} k x^2 \]
where \( k \) is the spring constant and \( x \) is the amount of stretch (elongation).
