Use Gauss’s Law to find the electric field at an arbitrary position r in the hollow region (ρ =0) between two concentric conducting cylinders. The inner cylinder has radius a and bears a constant charge per unit length, λ, while the outer cylinder has inner radius b and bears the same charge per unit length.

Equation:

Solution:

Not really sure, where to go with this from a geometric point of view.
