Two infinitely long thin straight wires having uniform linear charge densities `lambda` and `2lambda` are arranged parallel to each other at a distance r apart.The intensity of the electric field at a point midway between them is

Explanation

To solve the problem of finding the intensity of the electric field at a point midway between two infinitely long straight wires with uniform linear charge densities \( \lambda \) and \( 2\lambda \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Setup**:
- We have two infinitely long straight wires parallel to each other.
- The distance between the wires is \( r \).
- The linear charge density of the first wire is \( \lambda \) and that of the second wire is \( 2\lambda \).
