A long electricity distribution line is running current due east from the power plant to one of its substations. Earth's magnetic field points roughly South-to-North throughout this entire area, but its magnitude varies from 25 µT near the plant to 64 µT near the substation. If the part of the line near the plant feels a force per unit length of 5.93 x 103 N/m due to Earth's magnetic- field, then what force would be felt by a 200 m section of line located near the substation? Be sure to specify the magnitude and direction of the force in question.
