A parallel-plate capacitor is formed of two 10 cm x10 cm plates spaced 1.0 cm apart. The plates charged to +/-1.0 nC. An electron is shot through a very small hole in the positive plate.
a) Find the magnitude and direction for the electric field E generated by the parallel plate capacitor.
b) What is Fel on the electron inside the parallel plate capacitor.
c) What is the slowest speed the electron can have if it is to reach the negative plate?
