![**Title: Applying Gauss's Law to Determine the Electric Field of a Large Conductor**
**Objective:**
Learn how to use Gauss’s Law to find the electric field at a specified point near a conductor.
**Theory and Concept:**
Gauss's Law states that the net electric flux through a closed surface is equal to the charge enclosed divided by the permittivity of free space (ε₀).
**Problem Statement:**
Determine the electric field at the field point for a semi-infinitely large conductor with a surface charge density \( \sigma \). The distance between the field point and the surface of the conductor is \( d \).
**Illustration Description:**
- **Diagram Overview:**
- **Axes:**
- The vertical axis is labeled \( z \).
- The horizontal axis is labeled \( x \).
- **Conductor:**
- A grey rectangle represents a semi-infinitely large conductor along the x-axis.
- The top surface of the conductor has positive charges denoted by plus signs (+).
- The surface charge density is indicated as \( \sigma \).
- **Field Point:**
- A point labeled "Field point" is marked above the surface of the conductor.
- The field point is at a distance \( d \) from the charged surface along the z-axis.
**Solution Approach:**
1. **Conceptualize the Problem:**
- Consider a Gaussian surface (such as an imaginary box or cylinder) that encloses the charge distribution and extends through the field point.
2. **Apply Gauss's Law:**
\[
\Phi = E \cdot A = \frac{Q_{\text{enclosed}}}{\varepsilon_0}
\]
Where:
- \( \Phi \) is the electric flux.
- \( E \) is the electric field magnitude.
- \( A \) is the area through which the field passes.
- \( Q_{\text{enclosed}} \) is the charge enclosed.
- \( \varepsilon_0 \) is the permittivity of free space.
3. **Calculate the Electric Field:**
- Use symmetry and the geometry of the problem to simplify calculations.
- For a planar surface with charge density \( \sigma \), the electric field \( E \) is:
\[
E = \frac{\sigma}{2\varepsilon_](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F34799c9d-51c9-44f4-abf6-6899f662eb92%2Fd418db41-138b-4c03-814b-e686fd8950eb%2Fxh1tgvd_processed.png&w=3840&q=75)
