Particle launched along the central axis of a uniformly charged disk.
A thin, flat, circular insulating disk of radius \(R\) carries a total positive charge \(Q\) distributed uniformly over its surface. A small particle of mass \(m\) and positive charge \(q\) is launched from the center of the disk along its central perpendicular axis. Which of the following expressions represents the minimum launch speed \(v_0\) required for the particle to escape to an infinite distance from the disk?
