The charges and coordinates of two charged particles held fixed in an xy plane are q, = 2.48 µC, x1 = 4.85 cm, y, = 0.696 cm and 92 = -5.01 µC, x2 = -2.67 cm, y2 = 1.35 cm. Find the (a) magnitude and (b) direction (with respect to +x-axis in the range (-180°;180°]) of the electrostatic force on particle 2 due to particle 1. At what (c) x and (d) y coordinates should a third particle of charge q3 = 4.44 µC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero?
