A beam of electrons is accelerated through a potential difference of 10 kV before entering a region having uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the direction in which the electron is moving. If the magnetic field in this region has a value of 0.010 T, what magnitude of the electric field is required if the particles are to be undeflected as they pass through the region?

• 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...
