You have two conducting charged plates parallel to each other and separated from each other by a small gap. For simplicity, we can consider them to be two charged planes. One plane has a very strong, positive charge. The other, a weak, negative charge. If you are far enough from the negative plane (inverse square law means that if you are too close, the field from the negative will be very strong), will you be able to feel the electric field from the positive plane through the negative plane? And no, this is NOT homework.
