Three point charges, Q1, Q2, and Q3 are arranged in a triangle as shown in the figure. Point charge Q has a charge of 5.16 nC. Point charge Q2 has a charge of 5.52 nC. Point charge Q3 has a charge of 1.85 nC. Point charges Q1 and Q are separated by a distance D12 of 0.136 m. Point charges Q2 and Q3 are separated by a distance D23 of 0.545 m. Point charges Q1 and Q3 are separated by a distance D13 of 0.598 m. n + What is the electrostatic potential energy Utot of this configuration of charges? Utot = Assume that zero of potential energy corresponds to all the charges being infinitely far apart. D13 D12 22 TOOLS D23 J
