In the figure particle 1 of charge $q_1 = 1.02 \mu C$ and particle 2 of charge $q_2 = -3.00 \mu C$, are held at separation $L = 9.8 \text{ cm}$ on an x axis. If particle 3 of unknown charge $q_3$ 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?
(a) Number -13.8 Units m
(b) Number 0 Units m
