A ring of negative, uniform charge density is placed on the xz-plane with the center of the ring at the origin. A positive charge moves along the y axis toward the center of the ring. At the moment the charge passes through the center of the ring

Question

Quizplus · Accepted Answer

At the center of the ring, the electric field is zero due to symmetry, so the acceleration is zero. The velocity is maximum because the charge has been accelerating towards the center.
