Consider two point charges <i>q<sub>1</sub></i> and <i>q<sub>2</sub></i> lying on the <i>x</i>-axis.  
Consider a third charge <i>q<sub>3</sub></i> located somewhere near <i>q<sub>1</sub></i> 
and <i>q<sub>2</sub></i>.  Assume that the net force exerted by these charges on <i>q<sub>3</sub></i> 
is zero.  This implies that <i>q<sub>3</sub></i> <strong>must</strong> lie somewhere along the 
<i>x</i>-axis.
