Normally I don't post solutions to Rec. assignments, but this MAPLE assignment was especially tricky. The way to avoid a misnaming of variables comes from the command "assign". If you are interested take a look at the solution (right-click and save-as). Have a good weekend!
No need to waste a PDF on this one, your recitation assignment can be stated quite simply. Given a dipole orientated on the x-axis, numerically show that Gauss law holds over a cube bounding the charges. No need to give numbers here (dipole separation, charge, size of box, etc...) because it shouldn't matter! It may be useful to use Visual Python to plot the E-Field before you try to integrate, but it is not necessary. Good luck!
Your midterm is Wednesday, May 7th during your normal recitation time. It may be a good idea to review HW and course notes. The solutions to (HW 1,2,3) assignments can be found in the sidebar. Good luck!
Due on Friday, April 25: Chapter 19 Review questions 47, 52, problems 66, 67, 69, 71, 73
Chapter 18, review question 41 (Present a table with headings "experiment, effect on current, parameter." You must explain your answers!), problems 45, 46, 50, 51 (also graph the potential V and electron current i for all at points A-F around the circuit), 56
