b. How does Coulomb’s law apply to situations in which there are more than two point charges? Charge EM HW-88 2. Coulomb's law allows us to find the force between two point charges. t9 Three point charges are held fixed in place as shown. 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," a. Do you agree with this statement? Explain. 4. 3.
