A clock face has negative point charges -q, -2q, - 3q, . . . , - 12q fixed at the positions of the correspond- ing numerals. The clock hands do not perturb the field. At what time does the hour hand point in the same direction as the electric field at the center of the dial? (Hint: Consider dia- metrically opposite charges.)
