# Why cosine theta for calculations?

1. Dec 5, 2005

When figuring the force between 2 points, no angle the result is calculated just by distance (and charge). But when there are 3 points, either 2 charges or more and a point or 3 charges, why is there an angle calculation?

I think a good start would be to state the problem clearly. Your description of it is a bit vague.
