Two wires of equal cross section but one made of steel and the other of copper, are joined end to end. When the combination is kept under tension, the elongations in the two wires are found to be equal. Find the ratio of the lengths of the two wires. Young modulus of steel `=2.0xx10^11Nm^-2` and that of copper `=1.1xx10^11Nm^-2`

Explanation

To solve the problem, we will use the concept of Young's modulus and the relationship between stress, strain, and elongation in the wires.

### Step-by-Step Solution:

1. **Identify Given Data:**
- Young's modulus of steel, \( E_S = 2.0 \times 10^{11} \, \text{N/m}^2 \)
- Young's modulus of copper, \( E_C = 1.1 \times 10^{11} \, \text{N/m}^2 \)
- Let the lengths of the steel and copper wires be \( L_S \) and \( L_C \) respectively.
