A long straight wire carries a current of 6.2 A. The wire is horizontal in the plane of the page (screen) and the current is traveling to the left. An electron is 2.9 cm above the wire and moving toward the wire at a speed of 4.60x106 m/s.
a. Calculate the force that acts on the electron?
b. What is the direction of the force? e (electron)
