How do I calculate the voltage across each capacitor after the switch is closed?

Homework Statement

Personal question: What is the voltage across each capacitor after the switch is closed?
(It was previously calculated that the current after the switch is closed is .5 A)

Homework Equations

Q = CV
Q = Qo*e^(-t/RC)
V = IR

The Attempt at a Solution

The answer is 20 V for the 5uF capacitor, but I do not understand why the voltage for the 5 uF capacitor is the same as the voltage across the 40 ohm resistor.

I have no idea how to calculate the voltage for the 10 uF capacitor.

Presumably you're looking for the voltage across the capacitors a "long time" after the switch is closed, after the transients have died away and everything is static?

Consider that at that time the currents through the capacitors will all be zero (we've reached steady state for a DC circuit) , so as far as the resistance network around the capacitors is concerned, the capacitors no longer exist. See if you can identify a resistive voltage divider that's setting the final voltages at key points in the circuit.
