Attractive and repulsive forces from net charges

  1. Feb 25, 2015 #1
    How do you determine the force between two objects based on their net charge. For example, if you have a charged balloon and you know the value of that charge and the distance it is away from a neutrally charged wall, how can the attractive force between the wall and balloon be determined?

    For there to be attraction or repulsion between two charged bodies, the basic requirement is that the bodies have a CHARGE. So what do you think will happen in case of the neutrally charged wall?
