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.

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)


?
