In the figure particles 2 and 4, of charge -e, are fixed in place on a y axis, at y₂ = -8.30 cm and y4 = 4.15 cm. Particles 1 and 3, of charge - e, can be moved along the x axis. Particle 5, of charge +e, is fixed at the origin. Initially particle 1 is at x₁ = -8.30 cm and particle 3 is at x3 = 8.30 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° (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate back to its original counterclockwise? direction? (a) Number (b) Number i Units Units 3
