Two particles are fixed on an x axis. Particle 1 of charge 40 micro-coulombs is located at x =-2.0cm; particle 2 of charge Q is located at x = 3.0 cm. Particle 3 of charge magnitude 20 micro-coulombs is released from rest on the y-axis at y=2.0 cm. What is the value of Q if the initial acceleration of particle 3 is in the positive direction of
