Question

Consider two identical simple RC circuits each composed of a
capacitor ( 2.31 mF), a resistor ( 28.2 kΩ), and a constant DC source
( 25.8 V). At time t = 0, one capacitor, initially fully charged, is made to discharge through the resistor in its RC circuit, with the DC source
disconnected. At the same time, the other capacitor, initially uncharged,
is made to charge through the DC source in its RC circuit, with the
connected resistor. The time at which the two capacitors will have equal
charge is most nearly
