Homework Help: Charge between two metal plates

  1. Feb 7, 2017 #1
    1. The problem statement, all variables and given/known data
    Two large metal plates of area 1.1 m^2 face each other, 6.2 cm apart, with equal charge magnitudes but opposite signs. The field magnitude E between them (neglect fringing) is 50 N/C. Find |q|.

    2. Relevant equations

    3. The attempt at a solution
    I thought that after I did the rearranging of formulas above that this would be a pretty simple problem

    It seems that I used coulombs constant instead of the permittivity of free space
