Determine the motion of a charge passing through an electric field. Suggested Study Procedures Study Secs. Although you won't be asked in the course to perform integrations such as these, we will refer to these results later in the course. 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. You are encouraged to discuss the homework problems with other students, but you are expected to prepare your own solutions for submission. 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.
