A conducting sphere of radius R carries an excess positive charge and is very far from any other charges.Which one of the following graphs best illustrates the potential (relative to infinity)produced by this sphere as a function of the distance r from the center of the sphere?

The electric potential produced by a conducting sphere with excess charge due to its configuration is given by V(r) = kQ/r. Since the sphere is very far from any other charges, we can assume that r is much greater than the radius of the sphere. Therefore, the potential is approximately inversely proportional to the distance from the center of the sphere, which means it decreases as the distance increases. Thus, option D is the best choice as it shows the inverse proportionality of potential with distance.
