    You have a hoop of charge of radius R and total charge -Q. You place a positron at the center of the hoop and give it a slight nudge in the direction of the central axis that is normal to the plain of the hoop. Due to the negative charge on the hoop, the positron oscillates back and forth. Step 1: Clearly show how to use integration to find the z-axis E-field of a ring charge. Step 2: Place a...

    A small bead of mass m can slide without friction on a circular hoop that is in a vertical plane and has a radius R. The hoop rotates at a constant angular velocity ω about a vertical axis through the diameter of the hoop. Our goal is to find the angle β, as shown, such that the bead is in vertical equilibrium. We break the problem into several steps. a) Assume the bead is in vertical equilibrium and does not...
