Some electrostatic air cleaners consist of parallel metal plates with wire electrodes running between them as sketched in Figure P18.88. These air cleaners act by first ionizing a dust particle and then attracting it to one of the plates. If the plates are 10 cm apart and the electric potential difference between a wire and the neighboring plates is 4000 V, what is the approximate magnitude of the electric field inside the air cleaner?
