Oct 12, 2009 · Charge is placed on two conducting spheres that are very far apart and connected by a long thin wire. A negatively charged rod is placed next to the right sphere. The charge \(Q\) that was originally on the larger sphere distributes itself onto the two spheres. diffferent potential The radii of two charged metal spheres are 5 cm and 10 cm both having same charge 75 mC. So, if we take two separate points in the wire (and let's assume these two are really far from one of the spheres so that the electric potential of that sphere can be neglected for this There are two conducting spheres of different charge and a conducting wire. The magnitude of the electric potential of sphere A and more. Since the two spheres are connected by a wire, their potential (V) will become equal. Both spheres are charged and connected through a wire. Before connecting the spheres, the one with radius \(a\) is charged with a total charge of \(Q\), while the second one is uncharged. Two charged metal spheres are connected by a wire, and sphere A is larger than sphere B as shown.
