Chapter 4, Problem 54P
An electron with charge Qe = −1.6×10−19 C and mass me = 9.1 × 10−31 kg is injected at a point adjacent to the negatively charged plate in the region between the plates of an air-filled parallel-plate capacitor with separation of 1 cm and rectangular plates each 10 cm2 in area (Fig. P4.54). If the voltage across the capacitor is 10 V, find the following:
- (a) The force acting on the electron.
- (b) The acceleration of the electron.
- (c) The time it takes the electron to reach the positively charged plate, assuming that it starts from rest.
