Hi All,

I have a simple physics question, which I wonder if somebody could help me
with as I am a computer science person trying to use Coulomb force as an
error metric.

In 3D space, if I have a charged rod, (length l with start and end points,
r1 and r2) and an oppositely charged particle positined at p1, what is the
coulomb force between them?

I am assuming you have to integrate the standard coulomb force between two
particles along the rod (Excuse the poor english),

Any help is much appreciated,

Adam
Yep but some of this may be done for you as solutions exist for the field
produced by a charged line of finite length. These could save you some work.
