Two small beads with positive charges

Reference no: EM13654281

Two small beads with positive charges+4q and+q are fixed atopposite ends of a horizontal insulating rod as shown. A third small charged bead is free to slide along the rod between the fixed charges.

a) At what position will the third bead be in equilibrium?
b) Under what condition, if any, would the equilibrium be stable?
