Two point charges Q1 = Q2 = +2.4 μC are fixed symmetrically on the x-axis at x = ±0.356 m. A point particle of charge Q3 = +3.7 μC and mass m = 12 mg can move freely along the y-axis. If the particle on the y-axis is released from rest at y1 = 0.016 m, what will be its speed, in meters per second, when it reaches y2 = 0.074 m? Consider electric forces only.
