Part 4: A circular conductor and one conductor plate that are oppositely charged 1) Examine the photo in fig. 5 below for a cylinder conductor and a plate oppositely charged. Threads were placed suspended in oil to map the electric field lines. 2) What do you notice about the electric field inside the cylinder? 3) What do you notice about the angle between the electric field line and each point on the surface of each conductor? 4) Some of the field lines for a conductor circle and a conductor rod that are oppositely charged are sketched in fig. 6 below. According to your observation of the photo, and your answers to the questions in steps (2) and (3), answer the following about the few of the field lines that are sketched in fig. 6: a) Are the field lines Figure 5: Photo of a cylinder and a plate, oppositely perpendicular to the points of the surfaces of the conductors? charged. (From Serway, Physics for scientists and engineerss, 4th edition, Ch. 24, Saunders College Publishing, 1995. Photo is courtesy of Harold M. Waage, Princeton University) b) Would the equipotential line between points A and B be horizontal and parallel to the rod? Why? c) Will the equipotential between points C and D be a curve? Why?
