Effect of Neutral Conductor on a Point Charge?

Click For Summary
SUMMARY

The force on a point charge is always directed toward a neutral conductor due to the mobility of charges within the conductor. When a positive point charge is introduced, the negative charges in the neutral conductor move closer to it, creating a net attractive force. This interaction illustrates the fundamental principle of electrostatics where induced charges respond to external electric fields. Understanding this concept is essential for grasping the behavior of electric fields and forces in conductive materials.

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?

Thanks!

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!
