The charges and coordinates of two charged particles held fixed in an xy plane are q1 = + 3.0μC, x1 = 3.5 cm, y1 = 0.50 cm, and q2 = – 4.0μC, x2 = – 2.0 cm, y2 = 1.5 cm. Find the

(a) Magnitude and

(b) Direction 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 = + 4.0μC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero?
