What is the Capacitance of a Capacitor When a Conductor is Inserted?

[electricblue7]

Homework Statement

An isolated capacitor with capacitance C = 1 µF has a charge Q = 22 µC on its plates.
Now a conductor is inserted into the capacitor. The thickness of the conductor is 1/3 the thickness of the capacitor and is centered in between the plates of the capacitor.

What is the capacitance of the capacitor with the conductor in place?

Homework Equations

Q = C / V

V = E d

The Attempt at a Solution

I know that since the capacitor is a conductor it makes the distance between the two plates smaller which means that the capacitance should therefore increase. I thought that since we now had two distances that were each 1/3 the original distance the capacitance would increase by a factor of 6 however this answer does not work. Can anyone help me please?!?

After introduction of conductor, each capacitor is three times the original capacitor. Now these two capacitors are in series. Then what will be the combined capacitor?
