I'm looking for a quick and dirty was to calculate an electric field.
I know this shit should be easy, I just have to work it out.
Problem) Calculate the electric field between the 2 charges on the x axis:
2 /\ / \ / \ 0----1
0 = 8.00nC 1= -5.00nC 2= 3.00nC
it's an equilateral triangle.
the distance between 0 and 2 is .500m
the angle at 0 is 60 degrees.
someone help a nigga out.

that's not the kind of help i need.
it might as well be written in Arabic. 9/5/2007 7:23:05 PM |

DH Hill, 6th floor, North Stack, QC21 is where you need to look lol
It's right behind me so I'll go see what I can find 9/5/2007 8:13:01 PM |

Do you at least have this equation?
This will give you the force the particle is creating at the origin (push or pull). Treat that similar to the magnitude of a vector and the sum them together.

im rollin with F=(ke) ( |8.00nC||-5.00nC| / .500^2)
...

I think you have the right formula, you need to sum the charges and then COS(60) to give you the magnitude (along X).
ke = 1/(4PIe0)
It's been a while since I've done these. They're pretty easy.
What book are you working out of?

i was multiplying charges
and not cos(shit)
lol.
so just add 8 + -5, divide by .5 for the first part of the answer.....
and the second part of the answer is cos(60)
