The charges and coordinates of two charged particles held fixed in an xy plane are q = 3.47 C, x = 3.16 cm, y = 0.763 cm and 92 = -3.30 , x2 = -2.84 cm, y2 = 1.26 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 93 = 3.96 C be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero?
