Two particles are fixed on an x axis. Particle 1 ofcharge 51.4 μC is located at x = -22.8 cm; particle 2 ofcharge Q is located at x = 10.8 cm. Particle 3 ofcharge magnitude 20.8 μC is released from rest on the yaxis at y = 22.8 cm. What is the value of Q ifthe initial acceleration of particle 3 is in the positive directionof (a) the x axis and(b) the y axis?
