Dual plate capacitor with two dielectric slabs

[EMishard]

Homework Statement

Dual plate capacitor with two dielectric slabs placed between the capacitors and a battery supply's a voltage across the capacitors. The slabs are not equal in dielectric permeability. What is the charge at the interface of the two slabs?

Homework Equations

The Attempt at a Solution

Would the charge be zero between them since insulators don't let charge through or would there be a way for the charge to develop between them? I can't find any information talking about the space between them.

You could have a look at what happens to polarization charges.

1. It's permittivity, not permeability.

2. Are the two dielectric slabs touching each other?
