Suppose you have two parallel, metal plates that have an electric field between them of strength 3.0 x 104 N/C, and are 0.050 m apart.
Consider a point, P, located 0.030 m from plate A, the negatively charged plate, when answering the following question.
a. What is the electric potential at P relative to plate A?
