. An electron is placed with an initial velocity of 3.00 m/s east in a region of space which has either an electric or magnetic field present. For each part of this question, find the force on the electron (magnitude and direction) and describe what the effect will be on the electron’s trajectory. Will the trajectory be linear, circular, helical, or something else? Will the particle speed up, slow down, or have constant speed? Make sure to explain all answers with computations or written explanations. a. The region has an electric field of 42.0 N/C east and no magnetic field. Force: Shape of trajectory: How the speed changes: b. The region has no electric field and a magnetic field of 870 µT east. Force: Shape of trajectory: How the speed changes: c. The region has no electric field and a magnetic field of 119 µT north. Force: Shape of trajectory: How the speed changes
