Three fixed beads are secured along the y-axis, with a bead of charge +nq at the origin and charges of -mq a distance a above and below the origin. The values of m and n can be set by an operator. On an insulating wire laid along the x-axis, a movable bead with
charge -pq is placed. By adjusting m and n, the movable bead can be moved to different equilibrium positions x along the wire. Your supervisor asks you to set up the system and test it. In particular, he asks for answers to the following questions.
(a) If n = 3 in a particular test, what is the value of m that will place the movable bead in equilibrium at x = a?
