Homework Statement

http://enjoy.phy.ntnu.edu.tw/data/458/www/simulations/sims5326.html?sim=John_Travoltage#ideas"
Hi, I am new here and I am taking Electro physics over at the University of Tennessee. I don't know how to integrate yet and i realized that i would need some help with this class.. I've read the chapter that this is over and i have a good idea of the answers, i would just like yall to check my work.

Homework Equations

A: What are the blue circles and why do they accumulate on him?
B:what and why do they settle if you quit rubbing his foot?
C: Quantitatively, how does john's mass if he gains a net charge of -.75 coulombs? Because of Conservation of mass, what lost the equivalent mass?
D:What happens as you move John's hand to the knob when he is strongly charged? why?
E :What would have happened if john was holding the knob as you moved his foot across the carpet?
F: what would have happened if the knob had a rubber or ceramic handle?
G You touch john's foot very lightly (under 15 charges) and hold his hand out to the knob. What happens and why?

The Attempt at a Solution

A: electrons, they get stripped of the carpet by rubbing his shoe on it.
B:They move mostly to one side of him, because one side of him becomes positive and the other negative?
C:no idea
D: The electrons get discharged to the door knob. Electrons are moving to a proton rich area?
E:Electrons flow from his feet and to the door handle.
F:The electrons would remain in his body.
G:Nothing, the door handle has enough electrons on the surface of it to repel the electrons in john?

Please check my answers out and help me expand mine if they don't seem very good, and thank you for your help

Welcome to the PF.

So were your answers correct?

Thanks for the welcoming. I don't know yet, Its part of a very large very difficult n assignment that is due Friday.

Ok, I am pretty sure i got this questions. i used diminsional analysis to solve for the weight change from the electrons.
