In the figure particle 1 of charge q1 = 0.95 μC and particle 2 of charge q2 = -2.99 µC, are held at separation L = 9.8 cm on an x axis. If particle 3 of unknown charge q3 is to be located such that the net electrostatic force on it from particles 1 and 2 is zero, what must be the (a)x and (b)y coordinates of particle 3?
