Order the following pictures so that they represent what happens to the surface charge distributions when a circuit is initially connected. (For example, a solution of ABCD would indicate that the surface charges start in the state shown in Image A, then move to the distribution shown in Image B, then C, and end in the state shown in Image D.)

Problem 2 - Point charge and plane (20 pts) A point charge q (q>0) is located a distance d above an infinite conducting plane lying in the x-y plane. The plane is connected to the ground (Fig.1), so that the electric potential V at any point on the plane satisfies V=0. Calculating the electric potential generated by the point charge-grounded plane combination at any point P is more complicated than it looks because the conducting plane pulls some electric charge...
