A moving particle encounters an external electric field that decreases its kinetic energy from 8740 eV to 7260 eV as the particle moves from position A to position B. The electric potential at A is -60.5 V, and the electric potential at B is +28.5 V. Determine the charge of the particle. Include the algebraic sign (+ or −) with your answer.
