A flat, circular, analog clock face has negative points charges -q, -2q, -3q, -4q,....., -12q fixed at the position of corresponding numbers. the clock hands do not perturb the net field due to the point charges. At what time does the hour hand point in the same direction as the electric field vector at the center of the dial? (hint: use symmetry)
