The circuit in the figure below contains two resistors, R1-1.8 kΩ and R2 2.8 k. and two capacitors, C1-1.7 μF and C3 = 2.5 μF, connected to a battery with emf ε-105 v. If there are no charges on the capacitors before switch s is closed, determine the charges q1 and q2 on capacitors C1 and C2, respectively, as functions of time, after the switch is closed.

A charging RC circuit controls the intermittent windshield wipers in a car. The emf is 12.0 V. The wipers are triggered when the voltage across the 110 µF capacitor reaches 10.0 V; then the capacitor is quickly discharged (through a much smaller resistor) and the cycle repeats. What resistance should be used in the charging circuit if the wipers are to operate once every 1.40 s? Answer in kΩ please. I need it ASAP. Thank you :)
