Two circular plates, each with a radius of 6.22 cm, have equal and opposite charges of magnitude 3.652 µC. Calculate the electric field between the two plates. Assume that the separation distance is small in comparison to the diameter of the plates. electric field: N/C The plates are slowly pulled apart, doubling the separation distance. Again, assume the separation distance remains small in comparison to the diameter of the plates. What changes occur with the electric field between the plates? The electric field decreases by a factor of 4. The electric field increases by a factor of 2. The electric field decreases by a factor of 2. The electric field increases by a factor of 4. The electric field stays the same.
