A moving particle encounters an external electric field thatdecreases its kinetic energy from 9820 eVto 7470 eV as the particle moves fromposition A to position B. The electric potentialat A is -51.0 V, and the electricpotential at B is +28.9 V.Determine the charge of the particle. Include the algebraic sign (+or −) with your answer.
