A beam of protons is moving in the direction with a speed
Chapter , Problem 36(choose chapter or problem)
A beam of protons is moving in the direction with a speed of through a region in which the electric field is perpendicular to the magnetic field. The beam is not deflected in this region. (a) If the magnetic field has a magnitude of and points in the direction, find the magnitude and direction of the electric field. (b) Would electrons that have the same velocity as the protons be deflected by these fields? If so, in what direction would they be deflected? If not, why not?
