Problem 1: A problem of practical interest is to make a beam of elec- trons turn a 90° corner. This can be done with the parallel-plate capac- itor shown in Fig.1. An electron with kinetic energy Ekin = 3.0 × 10-¹7 J enters through a small hole in the bottom plate of the capacitor. What strength electric field is needed if the electron is to emerge from an exit hole l = 1.0 cm away from the entrance hole, traveling at right angle to its original direction? For which distance d between the plates this is possible? (Answer: E = 3.75 x 104 N/C.) a) Which plate of the capacitor should be positive and which one should be negative if you want the electron to turn to the right? In Fig.1, draw the electric field created by the plates.
