Homework Help: I have a problem finding the permitivity of acetate, can some one help me

    1. The problem statement, all variables and given/known data
    The question goes as follows: A simple capacitor consists of two square sheets of aluminium foil separated by a thin sheet of acetate. The foil is 31.6 cm on a side and the acetate is 0.5 cm thick, with a dielectric constant k= 3.4

    What is the permittivity ε of the acetate sheet?

    2. Relevant equations
    q= CV C=kε(knot)A/d

    How is the dielectric constant defined in terms of permittivity of the material and permittivity of vacuum?
