Three point charges are fixed in the x-y plane, as shown in the figure. The charges are QA = + × 10-8 C, QB = + × 10-8 C, and QC = - × 10-8 C. The (x, y) coordinates of each charge and of a point P are indicated in the figure, with coordinates given in meters (m). What is the electric potential at point P (in V)?
