(a) Determine the net electric field at point P if the particles' respective charges are q1 = −3.00 nC, q2 = 4.00 nC and, q3 = 9.00 nC and their distances from the point are as indicated. Your answer must be in unit vector notation consistent with your coordinate system. (b) Determine the magnitude and the direction of the acceleration that an electron released from rest at P would initially experience.
