Do this one first. Determine the motion of a charge passing through an electric field. Suggested Study Procedures Study Secs. Suggested Study Procedures Study Sec. Electric field lines form a useful way to picture how the electric field behaves in space.
Field lines begin and end only on charges.
The number of lines beginning at a positive charge or ending at a negative charge is proportional to the charge. At each point along a field line the direction of the field line is parallel to the direction of the force experienced by a small positive test charge placed at that point. No two field lines can cross. While there will be no attempt to keep students from working with each other, blatant copying of the work of another will not help you learn the material, and will only lead to a sense of false security on examination work. Although the suggested problems are not to be turned in for grading, they are equally important as the assigned homework in mastering the course Objectives.
