A Copper wire of length 2.2m and a steel wire of length 1.6m, both of diameter 3.0mm are connected end to end. When stretched by a load, the net elongation is found to be 0.70 mm. Obtain the load applied . Young's modulus of copper is `1.1 xx 10^(11)Nm^(-2)` and Young's modulus of steel is `2.0 xx 10^(11)Nm^(-2)`.

Explanation

To solve the problem of finding the load applied to a copper wire and a steel wire connected end to end, we can follow these steps:

### Step 1: Understand the Problem
We have two wires: a copper wire of length \( L_c = 2.2 \, \text{m} \) and a steel wire of length \( L_s = 1.6 \, \text{m} \). Both wires have a diameter of \( d = 3.0 \, \text{mm} \) (which we will convert to meters). The total elongation when a load is applied is \( \Delta L = 0.70 \, \text{mm} \).

### Step 2: Convert Units
Convert the diameter from millimeters to meters:
\[
