We have two uniformly charged parallel plates, as shown. Their widths are much larger than the separation between the plates. The magnitudes of the charges on each are equal. a, b, and c indicate the regions just above, in between, and just below the plates, respectively. a)For the above situation, check each box that corresponds to a true statement. Select "None of the above" if none of them are true. A. The field made by either plate individually is given by σ/ϵ0 B. If both plates are positively charged, there is no electric field in region b. C. If the plates are oppositely charged, there is no electric field in region c D. If both plates have the same sign of charge, the fields they make cancel at the point exactly in between the plates, but nowhere else E. If both plates are negatively charged, the electric field in region a points towards the top of the page. F. None of the above. b)Now let's suppose that the plates are squares with side length 1.2 cm, and that they have equal and opposite charges of magnitude 2.3 μC. What is the magnitude of the electric field in region b?
