Help, physics emergency!!!!
Three point charges lie along the y-axis. A charge = -7.46 microCoulombs is at y = +6.43 m, and a charge = +8.29 microCoulombs is at y = +2.68 m. Where must a positive charge Q3 be placed such that the resultant force on it is 0 Newtons? Express your answer as a y-coordinate location (in meters).
