Two conducting spheres each given a charge q
WebPhysics questions and answers. Each of two small non-conducting spheres is charged positively, the combined charge being 40 mC. When the two spheres are 50 cm apart, each sphere is repelled from the other by a force of magnitude 2.0 N. Determine the magnitude of the smaller of the two charges. WebQ. A solid conducting sphere having a charge Q is surrounded by an uncharged concentric conducting spherical shell. Let the potential difference between the surface of the solid sphere and the outer surface of the shell be V. If the shell is now given a charge − 3 Q, the new potential difference between the same two surfaces is:
