Two cylindrical glass beads each of mass m = 12.3 mg are set ontheir flat ends on a horizontal insulating surface separated by adistance d = 1.53 cm. The coefficient of static friction betweenthe beads and the surface is ms = 0.201. The beads are then givenidentical charges (magnitude and sign). What is the minimum chargeneeded to start the beads moving?
