A large, negatively charged sheet -? is shown. A small charge q is a distance D just above this sheet. The small charge q experiences the effect of the negatively charged sheet as an electric force F_e1.

A second equally large, positively charged sheet ? is then placed a distance 2D above the sheet in the figure, to create a parallel plate capacitor. The small charge q experiences the effect of being ‘inside’ this parallel plate capacitor as an electric force F_e2.

Compare the magnitudes of the two electric forces on the small charge q in the two cases (is the magnitude of F_e2 greater than, less than, or equal to the magnitude of F_e1?). Explain your answer.
