A metre scale made of steel is calibrated at `20^C` to give correct reading. Find the distance between 50 cm mark and 51 cm mark if the scale ia used at `10^C`. Coefficient of linear expansion of steel is `1.1 xx 10^(-5) 0^C^(-5)`

Explanation

To solve the problem, we need to find the distance between the 50 cm mark and the 51 cm mark on a steel meter scale when it is used at a temperature of \(10^\circ C\). The scale was originally calibrated at \(20^\circ C\).

### Step-by-Step Solution:

1. **Understand the Problem**:
- The scale is calibrated at \(20^\circ C\) and gives correct readings at that temperature.
- We need to find the distance between the 50 cm mark and the 51 cm mark when the scale is used at \(10^\circ C\).
