2 of 5 1. Assume that an observer calculates electric field and potential by measuring the force on a test charge. This observer moves along the path described by the green arrow. Finally, assume the system is in vacuum. (a) Plot and justify E,V for a line charge of density pip arranged in a ring shape. The path goes through the center of the ring and is perpendicular to the ring area. Let us assume V = 0 is defined infinitely far away at z → 00. P1D Wire ring Observer path E V (b) Suppose the observer is far enough away that z » rg- Discuss whether it is appropriate to express E,V as if the ring charge were a point charge.

Consider the following capacitors under voltage constant condition. (a) Plot E, V through the capacitor, one with a dielectric slab and the other with a metal slab. The rest of the space is filled with vacuum. Let V = 0 be defined at the right capacitor plate. Pay special attention to making sure the different regions on the plots line up with the schematic.
