A long, straight wire carries a current of 2.70 A. An electron is traveling in the vicinityof the wire. At the instant when the electron is 4.44 cm from the wire and traveling with a speedof 7.00 104 m/s parallel to the wire inthe direction opposite to the current, what are the magnitude anddirection of the force that the magnetic field of the currentexerts on the electron? (Assume that the current runs left to rightand the electron is below the wire.)
