Coulomb's law allows us to find the force between two pointcharges. Three point charges are held fixed on a straight line withequal spacing; +Q, +q, -Q from left to right. Consider thefollowing comment about this situation. "There will be zero netelectric force on the charge in the middle due to the othercharges. Using Coulomb's law, the force due to the +Q charge ispositive, and the force due to the -Q charge is negative. The forcecancel." Do you agree with this statement? How does Coulomb's lawapply to situations in which there are more than two pointcharges?
