The figure shows a source that consists of three charged objects. Objects 1 and 3 are particles with charges q1 and q3, respectively. Object 2 is a sphere with charge q2. Point A is in the same plane as the source; its distance to each object is given in the figure. Use the numerical values in the figure to find the electric potential at point A. 92 = 20 nC 93 = 30 nC 2= 0.89 m 9 - 10 nC - 0,48 m 0.63 m A
