(solution) Two particles are fixed on an x axis. Particle 1 of charge 40.4

Two particles are fixed on anxaxis. Particle 1 of charge 40.4 ?C is located atx= -23.9 cm; particle 2 of chargeQis located atx= 8.43 cm. Particle 3 of charge magnitude 31.9 ?C is released from rest on theyaxis aty= 23.9 cm. What is the value ofQif the initial acceleration of particle 3 is in the positive direction of(a)thexaxis and(b)theyaxis?
