Find the net electric field in N/C at point P, where q1 = (7.543x10^0) nC, r1 = (3.115x10^-1) metres, q2 = (7.6830x10^0) nC and r2 = (2.68x10^-1) metres. You do not need to include a unit vector in your answer, but must include a minus sign if the field direction is in the negative x direction. 91 r P +X 12 92
