A long, straight wire carries a 13.0-A current. An electron is fired parallel to this wire with a velocity of 240 km/s in the same direction as the current, 2.30 cm from the wire.

Find the magnitude of the electron's initial acceleration.

What should be the magnitude of a uniform electric field that will allow the electron to continue to travel parallel to the wire?
