An electron is moving (at a particular instant) parallel to a wire with a speed of 3 × 105 m/s. The wire carries a current of 12 amps in the same direction as the electron moves.
(a) What is the force on the electron if it is 3 cm from the wire?
(b) Describe qualitatively the subsequent motion of the electron.
