Find the minimum charge needed to start the beads moving

Reference no: EM13707755

Question: Two cylindrical glass beads each of mass m = 20 mg are set on their flat ends on a horizontal insulating surface separated by a distance d = 5 cm. The coefficient of static friction between the beads and the surface is µs = 0.2. The beads are then given identical charges (magnitude and sign).

Part A: What is the minimum charge needed to start the beads moving?

I need help to find the minimum charge needed to start the beads moving.
