Physics 132, Sample Midterm Exam #2 Page 4 Problem 4. Following are several unrelated questions about various topics. (a) Which set of equipotential lines (light lines) and field lines (dark lines) is possible? (b) Consider the two positions marked P and Q underneath a large sheet of charge with charge density + σ , shown in cross-section. Which statement is true about the potentials at these two positions? A) V P < V Q B) V P = V Q C) V P > V Q D) V P = k σ /d, V Q = k σ/ 2d E) There is insufficient information to establish a relation between the potentials at P and Q.

[Don’t bother with equivalent capacitors, just consider the ones shown.] Parallel pairs: Series pairs: (d) Consider an isolated , charged parallel plate capacitor. If the distance between plates is doubled, how does the electric field between the plates change?
