ADVANCE STUDY ASSIGNMENT: COULOMB'S LAW PURPOSE of tl of this exercise is to become familiar with the force between electric point charges which is descrbed by Coulomb's law. In particular, we will investigate the force's inverse-square dependence on separation distance between charges. DISCUSSION A basic characteristic of electric charge is that charges exert forces on each other, like charges positive-positive and negative-negative) repel each other while opposite charges (positive- and constitute a Newton's third-law pair; that is, they are equal...

Points: 1 13) Is it possible to have a zero electric potential between two positive charges along the line joining the two charges? A) Yes, if the two charges are equal in magnitude. B) No, a zero electric potential cannot exist between the two charges. C) Yes, regardless of the magnitude of the two charges. D) cannot be determined without knowing the separation between the two charges E) cannot be determined without knowing the magnitude of the charges Points: 3...
