A parallel plate capacitor with area A and separation d, has a dielectric inserted in half of its volume. This capacitor is connected to a batter of voltage V and is fully charged. (second part is related to first so I had to post this as one question...I'm sorry)

What is the capacitance of the capacitor?

Force needed to start to pull out the dielectric?

How much energy is stored in this dielectric?

If we did manage to pull out this parallel plate capacitor with its flexible dielectric insert into a cylinder of outer radius R:

What is the capacitance of the capacitor?

Force needed to start to pull out the dielectric?

How much energy is stored in this dielectric?
