    • An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was before entering region 2. (a) Draw a physical representation of this situation, complete with the direction of the electric and...
