Problem 1: (Charges on a rectangle) Consider the following collection of charges below located around a a×b rectangle. Given that Q > 0, (a) Find the components of the net electric field, E→, at the point P, located at the center of the rectangle. (b) Find the magnitude of the electric field and sketch the components and net direction. (c) If an electron were to start at rest from this point would it accelerate? If so, in which direction would its acceleration be?
