1. The problem statement, all variables and given/known data 3. The attempt at a solution I know that the E-field is definitely affected by the presence of the space charges. Since one side is positive, the positive charges in the air get pushed towards the negative plate. so Enet = Eplate - Echarges But the thing is I don't know how the distribution of the charges will end up as, and hence how to calculate Enet.
