1. You've hung two very large sheets of plastic facing each other with distance d between them, as shown in the figure . By rubbing them with wool and silk, you've managed to give one sheet a uniform surface charge density n_1 = -n_o and the other a uniform surface charge density n_2 = 3n_o .
What is the field vector at each point? Give answer as a multiplier of n_o/epsilon_o.
2. E_cap = n/epsilon_o
3. So, for an ideal capacitor, E in between the two sheets is simply n/epsilon_o, and is zero outside because E_+ and E_- or of equal magnitude but opposite sign. So in this case, is the multiplier 4 for point 2, -2 for point 1, and 2 for point 3?
