Consider a parallel plate capacitor composed of two very large (approximate as infinite) square plates as shown in Figure 2. The actual area of the plates is 0.2 m2 and when a charge of 2.5 × 10 -6 C is placed on each plate (positive on one, negative on the other) they are found to store 3.1 × 10 -3 J of energy.
a) Draw electric field lines for this configuration of charge. You may draw on the figure, if you wish.
b) What is the distance between the plates (d, as shown in the figure)?
