What position is the third bead in equilibrium?

Reference no: EM13554805

Two small beads having positive charges 3q and q are fixed at the opposite ends of a horizontal insulating rod, extending from theorigin (the location of the larger charge) to the point x= d. As shown in the figure below, a third small chargedbead is free to slide on the rod. At what position is the third bead in equilibrium?
