The charges and coordinates of two charged particles held fixed in an xy plane are q1 = 3.10 ?C, x1 = 4.39 cm, y1 = -0.0920 cm andq2 = -3.81 ?C, x2 = -2.80 cm, y2 = 2.03 cm. At what (a)x and (b)y coordinates should a third particle of charge q3 = 4.83 ?C be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero?
