B. A region is surrounded by two infinitely long concentric cylinders of radii, a1 and a2 (a2>a1). The concentric cylinders are charged to potentials phi1 and phi2 respectively.
Determine the potential and electric field vector everywhere in the region.

Hello and thank you for posting your question to Brainmass!
The solution is attached below (next to the paperclip icon) in two formats. one is in Word XP Format, while the other is in Adobe pdf format. Therefore you can choose the format that is most suitable to you.
Note that I considered the potentials to be constant on teh cylinders.
I addition I used a for a1 and b for a2, thus teh outer cylinder radius is b.

Potential and Electric Field Vector of Two Concentric Charged Cylinders are investigated. The solution is detailed and well presented.
