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 4.30 cm from the wire and traveling with a speed of 6.10×10⁴ m/s directly toward the wire, what is the magnitude of the force that the magnetic field of the current exerts on the electron?

Part B

What is the direction (relative to the direction of the current) of this force?

opposite to the current

in the same direction as the current

perpendicular to the current
