Coulomb's law allows us to find the force between two point charges. Three point charges are held fixed on a straight line with equal spacing; +Q, +q, -Q from left to right. Consider the following comment about this situation. There will be zero net electric force on the charge in the middle due to the other charges. Using Coulomb's law, the force due to the +Q charge is positive, and the force due to the -Q charge is negative. The forces cancel each other out. Do you agree with this statement? How does Coulomb's law apply to situations in which there are more than two point charges?
1) Yes, I agree with the statement.
2) No, I do not agree with the statement.
3) Coulomb's law does not apply to situations with more than two point charges.
