Charges of 2 µC and 3 µC are 4 mm from each other. Raina’s group draws four diagrams trying to represent the electrical force between the charges. 4 pairs of charged particles. Each pair is labeled W, X, Y and Z respectively. A dot representing a charge of a positive 2 microcoulombs is on the left with a vector pointing left. A dot representing a charge on the right is labeled 3 microcoulombs with a vector pointing right. The pair is labeled W. A dot representing a charge of a positive 2 microcoulombs is on the left with a vector pointing right. A dot representing a charge on the right is labeled 3 microcoulombs with a longer vector pointing right. The pair is labeled X. A dot representing a charge of a positive 2 microcoulombs is on the left with a vector pointing right. A dot representing a charge on the right is labeled 3 microcoulombs with a vector pointing left. The pair is labeled Y. A dot representing a charge of a positive 2 microcoulombs is on the left with a vector pointing right. A dot representing a charge on the right is labeled 3 microcoulombs with a smaller vector pointing left. The pair is labeled Z. Which diagram is correct? W X Y Z.
