ECE 134 Introductory Field Theory Fall 2010 1 Reading Assignment: Cheng: Sections 3.7–3.11, 4.4 Schey: review material as needed Cartoon Guide: Chapters 14-15 Homework #2 Due: Monday 11 October 2010 1) A ring of charge density [C/m] is located in the z =0 plane and coaxial with the z -axis as shown at right. The ring has a radius a . Find the potential and electrical field along the z- axis . Exploit symmetry if you can to help simplify the problem. 2) Suppose a hollow conducting tube of radius a contains a uniform charge density in the region . The tube is grounded such that Volts. Find the field and potential inside by a direct integration of Poisson’s equation (see inside of back cover of Cheng for in cylindrical coordinates). This problem could also be solved using Gauss’ law, but I want you to use Poisson’s equation instead. 3) A vacuum-tube diode is shown at right. The cathode is hot and emits electrons into the region between two parallel plates, where they travel towards the anode. In operation at

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
