The following sequence of problems guides you through the calculation of the total electrie field at a target point in space when there are two source partieles. We'll stick to two dimensions (get rid of the z-axis) just to reduce some of the arithmetic. The source partieles are both located on the z-axis with source 1 at z = 5 em and source 2 at za = -5 cm. Source 1 has charge -5 uC while source 2's charge is 3 uC.
