# Time and tide waits for no man!

A clock face has negative charges $$-q,-2q,-3q,-4q,\ldots, -12q$$ fixed at the position of the corresponding numericals on the dial. The clock hands do not disturb the net field due to point charges.At what time does the hour hand point in the same direction as electric field at the centre of the dial?

All parts of the clock are of non conducting material.
