Problem
Three isolated conducting spheres have identical radii. Sphere P is at +300 V, sphere Q is at +150 V, and sphere R is at –50 V (all relative to infinity). Spheres P and R are briefly connected by a conducting wire and then separated. Afterward, which sphere (P, Q, or R) is at the highest electric potential?
