Three point charges are arranged in a triangle as shown in the figure. D12 . Point charge Q1 has a charge of 4.56 nC. + . Point charge @2 has a charge of 5.92 nC. . Point charge @3 has a charge of 2.25 nc. - + . Point charges Q1 and @2 are separated by a distance D12 of 0.146 m. . Point charges @2 and @3 are separated by a distance D23 of 0.605 m. D 23 . Point charges @1 and @3 are separated by a distance D13 of 0.618 m. D 13 What is the electrostatic potential energy Utot of this configuration of charges? Assume that zero potential energy corresponds to all the charges being infinitely far apart. 1.71 x10-6 Utot = Incorrect
