Electric charge in parallel plate capacitor with 2 parallel dielectrics

[AndrejN96]

Homework Statement

My question is: If we have a parallel plate capacitor with 2 parallel dielectrics both taking A/2 of the complete surface, is the total electric charge equal to sum of the electrical charges in the first dielectric and the second dielectric, i.e is q_total=q₁+q₂=σ₁*A/2+σ₂*A/2?

Homework Equations

C_total=C₁+C₂

Aren't dielectrics supposed to be neutral ?
Try to find something the two halves have in common.
Re problem statement: what are parallel dielectrics in this context? Are there two capacitors side by side or is there a stack of two dielectris between two capacitor plates ?

Re equations: Try to find something the two halves have in common and find equations that involve it
