  7. We believe in electric fields as physically real because there is an influence that can be independent of the particle that created the field .

  8. Field Lines of Electric Dipole

  9. If I put a charged point particle (blue dot) on a field line, then the particle will move so as to follow the field line. A True B False

  10. At which point is the electric field stronger? • Point A. • Point B. • Not enough information to tell.

  11. Can Electric Field Vectors Cross? (A) Yes (B) No (C) No idea

  12. Which is the electric field direction at the black dot? E. None of these. Slide 25-101

  13. What is the direction of the electric field at the dot? E. None of these. Slide 26-22
