Consider a charge Q1 of +2.5 C located at the origin (0,0) in the xy-plane. Coordinates are in units of meters. A. (15 points) How much work is done on a charge Q2 of -1.5 C to move it from infinitely far away to coordinates (6, 0)? Is the Electric Field doing the work? Explain your answer. B. (15 points) We now have two charges on the x-axis. Find the coordinates for a point on the x-axis where the electric potential is zero. C. (15 points) Point P is located at (0,-8). Find the magnitude and direction of the electric field at point P. D. (15 points) We'll now add a charge Q3 of +3.0 C at point P. Find the magnitude and direction of the electric force on Q3 due to Q1 and Q2.
