Physics Jan 28, 2021

Two small beads having positive charges q1 = 16q 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.(a) At what positionxis the third bead in equilibrium?
x=m

(b) Can the equilibrium be stable?

Yes, if the third bead has a positive chargeYes, if the third bead has a negative chargeNo
