Problem
Five vertices of a regular hexagon of side a carry identical charges +q, while the sixth vertex carries a charge −q of the same magnitude. Without detailed calculation, state whether the electric field at the centre of the hexagon is zero or non-zero. If it is non-zero, specify its direction with respect to the hexagon and give a brief justification.
