In Fig., particles 2 and 4, of charge -e are fixed in place on a y axis, at `y_(2) = -10.0 cm` and `y_(4) = 5.00 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 `x_(1) = -10.0 cm` and particle 3 is at `x_(3) = 10.0 cm` (a) To what x value must particle 1 be moved to rotate the direction of the net electric force `vec(F)_("net")` on particle 5 by `60^(@)` counterclockwise? (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate `vec(F)_("net")` back to its original direction ?

Explanation

(a) -402 cm, (b) 4.02 cm
