Friday, we'll be starting to discuss electric forces and fields. We'll skip most of the beginning of chapter 21 in your text, since it is fairly descriptive stuff you can easily read about, and dive right in to calculating electric forces. This would be the last few sections of Ch. 21, and the beginning of Ch. 22. I'll go over some questions on the HW set as well.
If you're having trouble remembering some of the vector manipulation, I did write a short math guide some time ago (and never quite finished, but close). Hopefully the quick tour of vectors on Wednesday didn't scare too many of you away ... we will start out slowly and work our way up to the harder things.
For Monday, you should have already read Ch. 21 and 22 (or skimmed them at least, let's be realistic here).
