MY NOTES ASK YO Beams of electrons can be steered using magnets. It is desired to change the trajectory of a beam of electrons by passing the beam through a magnetic field as shown in the diagram, where r= 4.80 cm. The electrons enter the magnetic field at A and leave the magnetic field at B. Region of magnetic field A Tr-B (a) Draw a diagram showing the path followed by the electrons while they are in the magnetic field, i.e. the path from A to B. (b) The electrons have kinetic energies of 4.34 kev. You may assume that the magnetic force is the only force acting on the electrons. The mass of an electron is 9.11 x 1031 kg.
