Question#03 A long, straight wire carries a current of 5.20 A. An electron is traveling in the vicinity of the wire. Part A At the instant when the electron is 4.40 cm from the wire and traveling with a speed of 6. 10x10* m/'s directly toward the wire, what is the magnitude of the force that the magnetic field of the current exerts on the electron? ANSWER: F . N Part B What is the direction (relative to the direction of the current) of this force? ANSWER: O opposite to the current in the same direction as the current perpendicular to the current
