Suppose the is an isolated charge (+1.5×10^-19C) that is displaced from point A to B due to the electric force. As the charge moves, it produces an electric field which has a magnitude of 6.9 N/C. Find the work done by the electric force of the original charge if it moves 1.5m from its original position
