Best ResponseYou've already chosen the best response.2You got the first one, as for the second one, remember that Protons are positively charged particle. Neutrons, as the name implied, has no charge. Electrons will be the opposite of protons, negatively charged.

Best ResponseYou've already chosen the best response.2You're right for Number 2, as for Number 3 is about the Milikan oil drop experiment and the charge on an electron is negatively charged which causes rise and fall by changing the voltage across the plates.
