For a Teflon™-filled, parallel-plate capacitor, the area of the plate is 50.0cm2 and the spacing between the plates is 0.50 mm. If the capacitor is connected to a 200-V battery, find (a) the free charge on the capacitor plates, (b) the electrical field in the dielectric, and (c) the induced charge on the dielectric surfaces.

find the sum of the two horizontal vectors and the sum of the two vertical vectors
