An electron travels with velocity < 0, 0, -2.6e6 > m/s in a region between a pair of very large charged plates, separated by a distance of 4.2 mm. In this region there is also a uniform magnetic field. The velocity of the electron remains constant throughout this region. The magnetic field, due to large coils outside the region, is measured and is found to be < 0, 0.22, 0 > T.
(a) What is the direction of the magnetic force on the electron?
(b) What is the direction of the electric force on the electron?
(c) What is the direction of the electric field in the region?
(d) What is the magnitude of the magnetic force on the electron?
(e) What is the absolute value of the potential difference between the plates?
