A moving particle encounters an external electric field that decreases its kinetic energy from 10360 eV to 7680 eV as the particle moves from position A to position B. The electric potential at A is -52.5 V, and the electric potential at B is +29.7 V. Determine the charge of the particle. Include the algebraic sign (+ or −) with your answer.
