Particle 1 of chrage +q and particle 2 of charge +9.00q are held at a separation L=9.00cm on an x-axis. If particle 3 of charge q3 is to be located such that the three particles remain in place when they are all released, what must be:
a)the ratio q3/q?
b)x-coordinate of particle 3? (Assume particle 1 is located at the origin of the system, and that the positive direction is to the right.)

Question

mew55 · Answer

i just need to know how to find the find the ratio.
i got the y to be 0 because of the origin
