Question:

Three very long wires are directed perpendicular to the plane of Figure P20.83. Each passes through the x–y plane a distance L from the origin, and each carries a current I that is directed out of the plane of the drawing. An electron is at the origin and has a velocity directed along +x. What is the direction of the magnetic force on the electron?
