5. Three spheres labeled A, B, and C are each suspended by an insulating thread. One of them is positively charged, another is negatively charged, and the other one is uncharged. A fourth sphere made of polythene is rubbed with a cloth and brought near (but not touching) each suspended sphere in turn. The following effects are observed: Sphere A = attraction Sphere B= repulsion %3D Sphere C= attraction %3D From the given observation, what is the nature of each of these spheres? What can you do to identify specifically the charge on each suspended sphere? 6. What is the force on an electron in an electric field of 500 N/C? kQ 7. Derive the unit of Epusing the equation E, 8. One thousand electrons are removed from a neutral pith ball. Find the magnitude of the charge.
