You can use either electric or magnetic fields to steer movingcharges. Suppose you have a beam of electrons moving in thexdirection with speed 1.0×107 m/s, and you want them to turn 30° totheir right in a distance of 1.00 cm.(a) [2 pts.] One way to turnthe electrons is to run them between two charged plates that are1.00 cm wide. There will be a uniform electric field between theplates. What direction does the electric field have to have to getthe electrons to turn to their right?(b) [2 pts.] What will be theshape of the path the electrons follow?(c) [10 pts.] What magnitudeof electric field is needed to get the electrons to turn by 30°?(d) [1 pts.] What is the difference in potential that you need toput across the plates, and which plate should be at the higherpotential?(e) [4 pts.] Another way to turn the electrons is toapply a magnetic field (instead of the electric field!). Whatdirection must the magnetic field have in order for the electronsto turn to their right?
