An electron travels with speed 1.0*10^7 m/s between two parallel charged plates. The plates are separated by 1.0 cm and are charged by a 200 V battery.
1. What magnetic field strength will allow the electron to pass between the plates without being deflected?
2. What is the direction of the magnetic field?
