Place a positively charged rod near the left sphere.
Explanation: With the two conductors connected, a positive rod brought near the left sphere attracts electrons to the left sphere and leaves the right sphere with a deficit of electrons (positive). While the rod is held in place, separate (insulate) the spheres and then remove the rod — the charges remain separated (left negative, right positive).
