If you determined the electric field intensity in a field using a test charge of 1.0×10 −6 C and then repeated the process with a test charge of 2.0×10 −6 C, would the forces on the charges be the same? What is the relationship between the direction of the electric field and the direction of the electric force?

If one of the plates is positively charged and the other negatively charged, the space between the plates will have a constant electric field except near the edges of the plates.
