The charges and coordinates of two charged particles held xed in an xy plane are (11 = 2.23 pC, x1 = 3.42 cm, Y1 = 0.189 cm and q; = ~4.99 uC,x2 = -2.02 cm, 3/2 = 2.10 cm. Find the (a) magnitude and (b) direction (with respect to +xaxis in the range (~180;180]) of the electrostatic force on particle 2 due to particle 1. At what (c) x and (d) ycoordinates should a third particle of charge Q3 2 4.72 pC be placed such that the net electrostatic force on particle 2 due to particles 1 and 3 is zero? (a) Number Units V (b) Number I Units V I (c) Number l Units v. (d) Number I Units v
