Minimum charge needed to start the beads moving

Reference no: EM13535555

Two cylindrical glass beads each of mass m = 32 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 3 cm. The coefficient of static friction between the beads and the surface is μs = 0.3. The beads are then given identical charges (magnitude and sign). What is the minimum charge needed to start the beads moving?
