I do understand how the force is split with cosine and sine. My problem is figuring out which angle to use. Is it similar to assigning force vectors in an inclined plane diagram?
Thanks!

Two identical charges q are placed on the x axis, one at the origin and the other at x = 5 cm. A third charge -q is placed on the x-axis so the potential energy of the three-charge system is the same as the potential energy at infinite separation. Its x coordinate is: (x=13)...
