The following items are associated with the electrostatics quiz from day 5. Review your quiz to see which items you need additional work on. Each task below will assist you in fixing misconceptions prior to taking the unit exam next class. For each question that you missed on the quiz, write a new correct explanation after discussing with your group.

For a review of the entire unit see this video.

Resources for each quiz question and ultimately the major concepts in the electrostatics unit are below.

  1. Describe and diagram the process of charge polarization. Use the following resources to assist with your explanation. (Video) (Reading)
