Two neutral, square, thin copper plates (15 cm per side) are situated parallel to each other and located 6 mm apart.  A 9V battery is connected to the plates, such that the anode is connected to one plate and the cathode to the other plate, and the battery and plates reach a new electrostatic equilibrium. What is the magnitude and direction of the electric field between the two plates? Two neutral, square, thin copper plates (15 cm per side) are situated parallel to each other and located 6 mm apart.  A 9V potential difference is applied across the two plates. What is the electric potential at a distance of 2 mm away from the negatively charged plate (define the negative plate to be at zero potential)?
