Homework Help: Magnitude of the electric field between the plates

  1. Nov 19, 2014 #1
    A uniform electric field exists between two oppositely charged parallel plates connected to a 13.0V battery. The plates are separated by 7.00x10-4 m.

    a) Determine the magnitude of the electric field between the plates
    b) If a charge of -4.29x10-6 C moves from one plate to another, calculate the change in electric potential energy of the charge.


    σ = Q / L² = 13.0 μC / (7.00x10^-4)²

    E = σ / ε₀
