# Physics, van de graff generators...

When a small metal ball with a charge is placed in an electrical field supplie dby a van de graff generator, it experiences a force from the generator, and thus it applies a reaction force. But does the ball also apply a force met with a reaction force of the generator?

Also, if the work required to move the ball is increased, how would you explain it if the voltage remains the same?

Yes. Force is always in pairs, equal and opposite...remember Newtons third law?

IT is the difference in voltage from where the ball started to where it ended that determines the work (unless some charge is lost).
