Consider two semi-infinite sheet with equal magnitude but, Ask an Expert

Academics

Consider two semi-infinite sheet with equal magnitude, but opposite sign, surface charge densities. The plates are 0.2 m apart and have a voltage of 3 V across them. An electron enters from left through hole at velocity v0 << c. What is the maximum kinetic energy the electron can have so that is does NOT hit the negative plate? 1 eV = 1.6 x 10^-19 Joules
