A parallel plate capacitor is formed of two squared plates each of side L, which are at a distance d apart from each other. The plates are charged with a +Q charge. An electron (charge -e and mass me) is shot through a very small hole in the positive plate as shown in the figure. What is the slowest speed the electron can have if it is to reach the negative plate? Make sure your answer is in terms of the given quantities only. Note: You can assume the electron is shot right at position of the positive plate and travels only inside the capacitor, you can neglect any motion outside the capacitor.
