Moving particle encounters an external electric field

Reference no: EM13556374

A moving particle encounters an external electric field that decreases its kinetic energy from 9460 eVto 7120 eV as the particle moves fromposition A to position B. The electric potentialat A is -51.0 V, and the electricpotential at B is +29.7 V.Determine the charge of the particle. Include the algebraic sign (+or −) with your answer.
