Step 1:

2.1.1)

Two capacitors are in series.

Substitute  microfarads,  microfarads.

Total capacitance is 3.1578 microfarads.

Solution :

Total capacitance is 3.1578 microfarads.

Step 1:

2.1.2)

From (2.1.1), total capacitance is 3.1578 microfarads.

Find the potential difference across each capacitance.

Now find the total charge .

.

Substitute and in the total charge.

The total charge is

Find the voltage across the capacitance .

Find the voltage across the capacitance .

The voltage across the capacitors  are and .

Solution :

The voltage across the capacitor is .

The voltage across the capacitor is .
