The charges and coordinates of two charged particles held fixed in an xy plane are q₁ = 2.23 μC, x₁ = 3.42 cm, y₁ = 0.189 cm and 92 = -4.99 μC, x2 = -2.02 cm, y2 = 2.10 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 = 4.72 μC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero?
