Two small beads having positive charges 91 = 299 and q2 = q are fixed at the opposite ends of a horizontal insulating rod of length d= 1.50 m. The bead with charge q₁ is at the origin. As shown in the figure below, a third small, charged bead is free to slide on the rod. 91 92 + (a) At what position x is the third bead in equilibrium? x = 0.87868 -0.879 m (b) Can the equilibrium be stable? Yes, if the third bead has a positive charge O Yes, if the third bead has a negative charge O No
