A plastic rod of length 2.2m and radius 3.6 mm carries a negative charge of `3.8xx10^(-7) C` spread uniformly over its surface. What is the electric field near the mid-point of the rod, at a point on its surface?

Explanation

To solve the problem of finding the electric field near the midpoint of a uniformly charged plastic rod, we will follow these steps:

### Step 1: Identify the given values
- Length of the rod (L) = 2.2 m
- Radius of the rod (R) = 3.6 mm = 3.6 x 10^(-3) m
- Total charge (Q) = -3.8 x 10^(-7) C

### Step 2: Calculate the linear charge density (λ)
