Two cylindrical glass beads each of mass m = 13.1 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 3.05 cm. The coefficient of static friction between the beads and the surface is ms = 0.197. The beads are then given identical charges (magnitude and sign). What is the minimum charge needed to start the beads moving?
