18 Net electric field Two hidden arrangements of charged particles each produce an electric field, i.e. one electric field vector at each point. These are illustrated at two points. The net electric field at any point is the sum of the two field vectors at each point. Use vector components to determine the net electric field at point A and the net 300 N/C electric field at point B. 20N/C A 500N/C

In Fig. 22-24, two particles +3q of charge -q are arranged symmetrically about the y axis; each produces an electric field at point P on that axis. (a) Are the magnitudes of the fields at P equal? (b) Is each electric field directed toward or away from the charge producing it? (c) Is the magnitude of the net electric field at P equal to the sum of the magnitudes E of the two field vectors (is it equal to 2E)?...
