What is the electric field intensity at any point on the axis of a charged rod of length 'L' and linear charge density `lambda`? The point is separated from the nearer end by a.

Explanation

To find the electric field intensity at any point on the axis of a charged rod of length \( L \) and linear charge density \( \lambda \), where the point is separated from the nearer end by a distance \( A \), we can follow these steps:

### Step-by-Step Solution:

1. **Define the Problem**:
We have a uniformly charged rod of length \( L \) with a linear charge density \( \lambda \). We need to find the electric field intensity at a point \( P \) located at a distance \( A \) from the nearer end of the rod.

2. **Set Up the Coordinate System**:
