21.82 • CP A small sphere with mass m carries a positive charge q and is attached to one end of a silk fiber of length L. The other end of the fiber is attached to a large vertical insulating sheet that has a positive surface charge density o. Show that when the sphere is in equilibrium, the fiber makes an angle equal to arctan (go/2mgeo) with the vertical sheet.
