###### Question details

In the figure particles 2 and 4, of charge –*e*, are
fixed in place on a y axis, at *y** _{2}* =
-8.16 cm and

*y*

_{4}= 4.08 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}= -8.16 cm and particle 3 is at

*x*

_{3}= 8.16 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?
