Derive an expression for electric field intensity E due to an infinite place sheet of charge.

Explanation

To derive the expression for electric field intensity \( E \) due to an infinite plane sheet of charge, we will follow these steps:

### Step 1: Define the Problem
Consider an infinite plane sheet of charge with a uniform surface charge density \( \sigma \) (charge per unit area). We need to find the electric field intensity \( E \) at a point \( P \) located at a distance \( d \) from the sheet.

**Hint:** Understand that the symmetry of the problem allows us to simplify the calculations.

### Step 2: Choose a Gaussian Surface
