A 1.00-km length of power line carries a total charge of 230 mC distributed uniformly over its length. Find the magnitude of the electric field 54.3 cm from the axis of the power line, and not near either end (staying away from the ends means you can approximate the field as that of an infinitely long wire). Express your answer with the appropriate units. E = Lo xa A Xb Value a b X.10n Units X ?
