Answer to Question #66510 in Electric Circuits for Chelsea
Anchorage, Alaska. The line is parallel to the ground and heading to the North (also
the direction of the electric current), but since the Earth is a sphere it means that

(see figure). Determine the force on a 20.0 m segment of the power line, and use the
right-hand rule to determine its direction.
