How can you characterize the electrostatic interaction? How do you define an electric field?

2: F 12/1 lab, 4: M 12/4 lab
 
Today, after a daily quiz, we'll tackle some problems on electric fields due to point charges from Chapter 21:
    Required: 37a, 38, 39, 40a, 41,  1981B32006aB3
    Enrichment:  Go on to problems below.  

Then, we'll continue to do some problems involving multiple point charges during the second hour.  (Note that these are from the AP Physics B test.  The C test questions will be more difficult, but this is a review of what you should have learned last year.)
    Required 2:  2000E2 (a-b), 1975B22002bB52003bB42006bB3 
You must do all of the parts of the problems which have to do with electric force and field, including the motion of a particle in the field.  Parts that have to do with potential energy, work, or potential are optional for now, but if you finish early, then try to remember how to do these parts.  

Homework:  If you need to review last night's video, make sure you do so.  Then watch this video on calculating the electric field due to a continuous distribution of charge.
