AI Generated Solution

To derive the expression for the electric field intensity at a point outside an infinitely long charged cylindrical conductor, we will use Gauss's law. Here’s a step-by-step solution: ### Step 1: Understand the Setup Consider an infinitely long charged cylindrical conductor with radius \( R \) and a uniform surface charge density \( \sigma \). We want to find the electric field \( E \) at a point outside the cylinder, at a distance \( r \) from the axis of the cylinder, where \( r > R \). **Hint**: Visualize the cylinder and the point outside it where you want to find the electric field. ### Step 2: Choose a Gaussian Surface ...
