Question
Two small beads having charges q1 and q2 of the same sign are fixed at the opposite
ends of a horizontal insulating rod of length d. The bead with charge q1
is at the
origin. As shown in Figure P22.8, a third small, charged bead is free to slide on the
rod. (a) At what position x is the third bead in equilibrium? (b) Can the equilibrium be
stable?
