The charges and coordinates of two charged particles held fixed in an xy plane are q1 = 2.16 JC, x1 = 4.49 cm, y1 = 0.925 cm and 92= -3.04 UC, x2 =-2.05 cm, y2 = 1.33 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 = 4.90 JC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero?
