Electric Forces and Electric Fields31(b) Any point on the x-axis in the range 0x<is located closer to the larger magnitude charge ( )5.00 Cqµ=than the smaller magnitude charge ( )4.00 Cq=. Thus, the contribution to the resultant electric field by the larger charge will always have a greater magnitude than the contribution made by the smaller charge. It is not possible for these contributions to cancel to give a zero resultant field. (c) If a point is on the x-axis in the region , the contributions made by the two charges are in opposite directions. Also, a point in this region is closer to the smaller magnitude charge than it is to the larger charge. Thus, there is a location in this region where the contributions of these charges to the total field will have equal magnitudes and cancel each other. 1.00 m
