= 17 The charges and coordinates of two charged particles held fixed in an xy plane are q₁ +3.0 μC, χι = 3.5 cm, y₁ = 0.50 cm, and 92 = -4.0 μC, 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 coordi- nates should a third particle of charge q3 = +4.0 μC be placed such that the net electrostatic force on particle 2 due to parti- cles 1 and 3 is zero? GO
