    Work done by electric force on a point charge in a cylinder?

    Homework Statement A point charge q is moved inside a hollow charged cylinder of radius R. The initial point A is a distance (3/4)R from the center and the final point B is at the center of the sphere. How much work is done by the electric force in this case? 2. The attempt at a solution I...
