  1. Hewitt Problems P. 676 3-9, 11-15 They both can attract, the equations that characterize them have a similar format, they are both dependent on the inverse square of the distance, both exert forces It has a value(we didn’t assign one) and a direction Lines that show an electric field. They represent the force a test charge would feel at a location

  2. 6. Here are some examples • 7. They are straight, parallel and evenly spaced, then around the ends it gets more complicated

  3. 8. Because the car’s metal shell would carry any electricity that might flow due to a lightning strike (not because of the rubber tires) • 9. a. gravity cannot be shielded • B. Yes, electric fields can be shielded • 11. Work = change in PE + any other types of energy, maybe some KE • 12. It gets transformed into KE

  4. 13. Electric Potential energy is all of the energy, Electric potential is all that energy divided by the number of charges, so Energy/charge • 14. More joules per more coulombs equals same electric potential.
