Two point charges Q1 = Q2 = +1.3 μC are fixed symmetrically on the x-axis at x = ±0.172 m. A point particle of charge Q3 = +4.8 μC and mass m = 13 mg can move freely along the y-axis.

a) If the particle on the y-axis is released from rest at y1 = 0.024 m, what will be its speed, in meters per second, when it reaches y2 = 0.065 m? Consider electric forces only.
