The circuit in the figure below contains two resistors, R, 1.9 kl and R₂-2.8 k, and two capacitors, C₁1.9 and C₂-3.1 af, connected to a battery with emf E-140 V. If there are no charges on the capacitors before switch 5 is closed, determine the charges e, and oy on capacitors C, and C₂, respectively, as functions of time, after the switch is closed. Hint: First reconstruct t circuit so that it becomes a simple RC circuit containing a single resistor and single capacitor in series, connected to the battery, and then determine the total charged a stored in the circut. (Use t given values for R₁, R₂, C₁, C₂, and E. Use the following as necessary: t. Do not include any units in your response) 91-42.8 269.8
