The figure below shows two uncharged metal balls, X and Y, supported on insulating stands. A third ball, Z, carrying a negative charge, is brought near the first two. A conducting wire is then run between X and Y. The wire is then removed, and ball Z is finally removed.

What is the final charge on the metal balls?

What would the charge on the two metal balls be if Z was removed before the wire was removed?
