Need An Answer For Number 4!

A circuit is constructed with four resistors, one capacitor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 41 ?, R3 = 110 ? and R4 = 84 ?. The capacitance is C = 71 ?F and the battery voltage is V = 24 V.

1)

The switch has been open for a long time when at time t = 0, the switch is closed. What is I1(0), the magnitude of the current through the resistor R1 just after the switch is closed?

.192 A

2)

What is I1(?), the magnitude of the current that flows through the resistor R1 a very long time after the switch has been closed?

.086A

3)

What is Q(?), the charge on the capacitor after the switch has been closed for a very long time?

922.006 ?C

4)

Consider the circuit above, with R5 = 74 ? in series with the capacitor. Once again, the switch has been open for a long time when at time t = 0, the switch is closed. What is I1(0), the magnitude of the current through the resistor R1 just after the switch is closed?
