(20 pts) 5. A conducting sphere of radius R carries a total charge of +Q. Its center is placed a distance 2R to the right of a grounded conducting plate. What is the potential at a general point (in terms of x, y, z and R) in space outside the sphere and to the right of the plane? (Carry out to at least four terms.) Hint:...image charge problem? (Note: remember you have a Q term and 1/r approx.. term to deal with don't forget both.) 2R +Q V=0
