An electron is moving in the vicinity of a long, straight wire that lies along the 3-axis. The wire has a constant current of 8.90 A in the -2-direction. At an instant when the electron is at point (0, 0.200 m, 0) and the electron 's velocity is ů = (5.00 x 104 m/s)i –(3.00 x 104 m/s)j. Part A What is the force that the wire exerts on the electron? Enter the x, y, and z components of the force separated by commas. Part B Calculate the magnitude of this force. Express your answer with the appropriate units. ?
