Electric charge placed at a point

  1. Feb 7, 2006 #1

    I know how to do the first question. The second question is what's troubling me. I don't know where the forces are supposed to be directed (i.e. to which charge)... basically i don't understand what I'm finding out.

    Any incite appreciated.

    There's a very simple relation that tells you the force acting on a charge placed in an electric field. What is it ?
