Problem

An electron of mass 9.11×10−31 kg9.11\times10^{-31}\,\text{kg} and charge −1.60×10−19 C-1.60\times10^{-19}\,\text{C} is released from rest at the negative plate of a pair of parallel plates separated by 1.0 cm1.0\,\text{cm}. The positive plate is at a potential 450 V450\,\text{V} higher than the negative plate. Assuming the field between the plates is uniform, calculate the magnitude of the acceleration experienced by the electron while it is between the plates.
