일반물리학 2 — Capacitance: Problem 42

42 Figure 25-38 shows a circuit section of four air-filled capacitors that is connected to a larger circuit. The graph below the section shows the electric potential \(V(x)\) as a function of position \(x\) along the lower part of the section, through capacitor 4. Similarly, the graph above the section shows the electric potential \(V(x)\) as a function of position \(x\) along the upper part of the section, through capacitors 1, 2, and 3. Capacitor 3 has a capacitance of \(1.60 \text{ \mu F}\). What are the capacitances of (a) capacitor 1 and (b) capacitor 2?
