A uniform field between two large, parallel flat plates, due to the horizontal position of the plates, is vertical. A small sphere, of mass m and which has a charge q, is attached to the end of a light rod which is attached at its other end to an axis parallel to the plates such that it can rotate freely around it. The sphere is placed in the central region (away from the edges) in the equilibrium position and then moved a short distance away and left at rest. b) Describe the subsequent movement if the top plate is negatively charged.
