### Electric Field Calculation for Linear Charge Density

**Problem Statement:**
The entire y-axis is covered with a uniform linear charge density of \( \lambda = 2.2 \, \text{nC/m} \). Determine the magnitude of the electric field on the x-axis at \( x = 5.5 \, \text{m} \).

Round your answer to 1 decimal place.

**Detailed Explanation:**
1. **Understanding the Setup:**
   - You have a uniform linear charge distribution along the y-axis. 
   - A linear charge density (\(\lambda\)) implies the charge per unit length along the y-axis.
   - You are asked to find the electric field at a point on the x-axis, \( x = 5.5 \, \text{m} \).

2. **Relevant Formulas:**
   - The electric field (\(E\)) due to a line of charge can be determined using the formula:
    \[
    E = \frac{\lambda}{2 \pi \epsilon_0 r}
    \]
   where:
   - \(\lambda\) is the linear charge density
   - \(r\) is the perpendicular distance from the line of charge to the point where the field is being calculated
   - \(\epsilon_0\) is the permittivity of free space (\(8.85 \times 10^{-12} \, \text{C}^2/\text{N} \cdot \text{m}^2\))

3. **Applying to the Given Problem:**
   - Given \(\lambda = 2.2 \, \text{nC/m}\) or \(2.2 \times 10^{-9} \, \text{C/m}\)
   - Distance \(r = 5.5 \, \text{m}\)

4. **Calculation:**
   Substitute the values into the formula to find \(E\):
   \[
   E = \frac{2.2 \times 10^{-9} \, \text{C/m}}{2 \pi (8.85 \times 10^{-12} \, \text{C}^2/\text{N} \cdot \text{m}^2)(5.5 \, \text{m})}
   \]
   Simplify the expression step-by-step:
   \[
