(4%) Problem 13: In a given coordinate system shown at right, a particle with charge q = 9.8 JC sits at the origin. The coordinates of point A are (0, 5) m. The coordinates of point B are (5, 0) m. The C coordinates of point C are (5, 5) m. The coordinates of point D are (5, -5) m. A (5, 5) (0, 5) q B (5, 0) D (5, -5) theexpertta.com 25% Part (a) How much work is done by the field in moving a proton from point A to point B in J?
