Effect of Neutral Conductor on a Point Charge?

  1. Oct 9, 2011 #1
    Why should the force on a point charge always be toward a neutral conductor? I know this is a simple concept, but I'm having trouble grasping it.

    Any ideas?

    Because a neutral conductor has both positive or negative charges which can move. If you have a + point charge, the - charges in the conductor move towards the + point charge and there is a net force.

    Oh, ok. I never thought of a neutral conductor in that way, but that makes a lot of sense! Thank you!
