: D 3 S F Three Particles Are Fixed On An X Axis Particle 1 Of Charge 91 Is At X A And Particle 2 Of Charge 92 Is 1 (25.18 KiB) Viewed 13 times

D {3 s.f.} Three particles are fixed on an x-axis. Particle 1 of charge 91 is at x = -a, and particle 2 of charge 92 is at x = +a. If their net electrostatic force on particle 3 of charge +Q is to be zero, what must be the ratio 91/92 when particle 3 is at x = +1.40a?
