Electron in a capacitor#
An electron enters a region between two large parallel plates made of aluminum separated by a distance of 3.0 \(\rm\ cm\) and kept at a potential difference of 220 \(\rm\ V\). The electron enters through a small hole in the negative plate and moves toward the positive plate. At the time the electron is near the negative plate, its speed is \(9.0\times 10^{4}\) \(\rm\ m/s\).
Question Text#
Assuming the electric field between the plates is uniform, find the speed of the electron when it is 2.6 \(\rm\ cm\) from the negative plate.
