A scale `(alpha=10^(-3)//.^(@)C)` gives correct reading at `0^(@)C` it is sued at a different temperature where the scale measured length 1.015 m line as 1m. Find the temperature in `.^(@)C`, at which this scale is used while taking the measurement.

Explanation

To solve the problem, we need to determine the temperature at which the scale gives a reading of 1 meter when the actual length is 1.015 meters. We will use the concept of linear expansion and the formula for strain.

### Step-by-step Solution:

1. **Understanding the Problem:**
- The scale gives a correct reading at 0°C.
- The scale measures a length of 1.015 m as 1 m.
- We need to find the temperature (T) at which this measurement occurs.
