1, Postive plate is correct. It takes work to move an electron from where it wants to go.
2. Poorly worded. If a conducting surface is at equal potential, the charge density at the point is higher due to the smaller surface area, which leads to a much higher Electric field at the point.
So I think maybe "higher" is what the author wanted, but it is higher charge density (due to smaller surface area). Maybe "concentration" is being used to indicate charge density.
1) When electrons are forced away from a/an ___ plate, work is done.
Is "positive" a possible answer?
2) Any pointed or angular surface of an object must have a/an ___ concentration of charge to establish equilibrium.
Any ideas?
