Parallel plates have an area of 28 cm2each, and are separated by 12 mm of air.  One has a positive charge of 9.5 mC on it, the other a charge of -9.5 mC on it.  

A. Draw the parallel plates, mark which plate is positive and which is negative, and draw the electric field between them.  (I’m expecting the edge-on view, but feel free to draw the 3-d version if you feel artistically ambitious.  You can just draw a few arrows in between the plates, you don’t have to do the edge effects for this one.  (You will next week.))

B. What is the magnitude of the electric field between the plates?  [3.83x108N/C]
