## Homework Statement

Note that am a beginner in physics,hardy know any,so be gentle (:

There are three particles in a line below.

The question is where must we put Q3 so it will get 0 total power.

Q1=6 mC

Q2=15 mC

Q3= -8 mC

In a line of 2 meters like this:

Q2-------------------------Q3-------------------------------Q1

(Q3 is anywhere between q1 and q2.

And that 3x is the two meter line.

## Homework Equations

I don't know what exactly to use,and since you here are far more experienced you will figure it out.

## The Attempt at a Solution

Couldn't even start it.sorry.Anyway,if someone has the patience to explain how this thing works it would be very appreciated.

Help the newbie.
