Consider the three charges in Figure 2. Each charge has magnitude of 1.0 nC. Their electric potential energy (using the usual reference potential energy) is a. 3.0×10−7 J b. 5.0×10−7 J c. 7.0×10−7 J d. 9.0×10−7 J e. None of the aboveConsider the three charges in Figure 2. Each charge has magnitude of 1.0 nC. The electric potential at the unoccupied corner of the rectangle, point P indicated with a dot (using the usual reference potential), is a. 3.0×102 V b. 5.0×102 V c. 7.0×102 V d. 9.0×102 V e.
