Actually the electric field is not between two cylinders, but it is in between a cylinder and a pipe, so it is not the same case as two parallel capacitors.

The solution This equation could be solved by replacing 2cos^2(\theta)\sin^2(\theta) with sin2(\theta). You will get an equation which is n^2 = \frac{1 \pm \sqrt{1-sin^2{2(\theta)}}}{2cos^2(\theta)} substitute 1 - sin^2{2(\theta)} with cos^2{2(\theta)} and manipulate the formula until...

But I wonder how hydrogen could behave like a metal in a high-pressure condition? What is the theory that leads to the magnetism inside the hydrogen core( if there is really a hydrogen core inside Neptunian Planet)? Hydrogen in normal condition exhibit diamagnetism, which mean it has very weak...
