**Problem Description:**

An infinitely long conducting cylinder with a radius of 2 cm has a linear charge density of \(+4 \, \mu\text{C/m}\). This cylinder is surrounded by an insulating shell with an inner radius of 8 cm and an outer radius of 12 cm. The insulating shell has a net linear charge density of \(+3 \, \mu\text{C/m}\). (Refer to Figure 1)

**Figure Explanation:**

The diagram illustrates a cross-sectional view of the system:

- **Central Cylinder:** Represented as a shaded, solid cylinder labeled "Central Cylinder" with a linear charge density denoted by \(\lambda_{\text{cyl}}\).
  
- **Insulating Cylindrical Shell:** Surrounding the central cylinder is a hollow, cylindrical shell labeled "Insulating Cylindrical Shell" with a linear charge density represented by \(\lambda_{\text{shell}}\).

**Visual Details:**

- The central cylinder is depicted with arrows pointing radially outward, indicating a positive charge distribution.
- The insulating shell is a larger cylindrical structure encompassing the central cylinder, also with arrows pointing outward.

This configuration is used to study electric fields and potential differences between charged cylindrical surfaces in theoretical physics and electrostatics.
