Electric charge in parallel plate capacitor with 2 parallel dielectrics

  1. Nov 7, 2014 #1
    1. The problem statement, all variables and given/known data
    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 qtotal=q1+q21*A/2+σ2*A/2?

    2. Relevant equations
    Ctotal=C1+C2

    3. The attempt at a solution

    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
    And please fill in the attempt at solution. We aren't allowed to assist otherwise. See PF guidelines
