Yes thank you very much.
Do you agree with Besh's answer for part iv?
I do however have some concerns over part v seeing as it seems you are over complicating the question. I'm thinking it may be answer e, due to the fact that I doubt they would introduce a non ohmic material at this level...
Read my pm, I can provide you with some help.
With part iv, I'm inclined to ask you for your working. How did you get to that value. And part v is a toss up between a,d,e :/
Maybe someone here can assist us with this.
--------------------------------
Basically with iv)
(2.7 x 10^3)/27 = 100...
Yeah I am, finding this paper tricky though.
As for parts iv and v, I'm fairly sure iv is wrong due to my highly crackpot calculations. I don't even think I have my 'working' anymore. I wouldn't submit the answer if I were unsure.
On v, I don't understand it but I thought other forces were in...
Yes thank you, you have provided me with enough information to understand the first three question parts.
I have a problem visualising it all, my physics lies in space not charges!
If you could point me in the right direction for the final two parts I would be most thankful.Thanks for your...
Thanks with this, your assistance is gratefully received. I don't want to appear pushy on these forums as it is other people's time being used.
Basically used your idea on
Part i
Potential = kq/r = [(8.99x10^9) x 30nC]/3
Then for charge point 2?
[(8.99x10^9) x -20nC]/root 13
add...
I'm hating Electromag as of late. To the extent I can't even understand these 'simplest' of questions. I don't want anyone to be doing my work for me as nothing is essentially accomplished that way. If someone could head me in the right direction with these questions, I'd be most grateful...
1. Info
Basically, I'm having trouble with this question and it's constituent parts.

Homework Equations
No equations for first two parts, it's the visualising that I'm finding tricky.
Part 3 will require some sort of...
