Use correct number of significant digits. The tolerance is +-1 in the 3rd significant digit

In the figure particles 2 and 4, of charge -e, are fixed in place on a y axis, at y2 = -9.84 cm and y4 = 4.92 cm. Particles 1 and 3, of charge - e, can be moved along the x axis. Particle 5, of charge te, is fixed at the origin. Initially particle 1 is at x1 = -9.84 cm and particle 3 is at X3 = 9.84 cm. (a) To what x value must particle 1 be moved to rotate the direction of the net electric force F net on particle 5 by 30 counterclockwise? (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate back to its original direction? 2 (a) Number Units (b) Number i Units
