External electric field-determine the charge of the particle

Reference no: EM13560505

A moving particle encounters an external electric field that decreases its kinetic energy from 9520 eV to 7060 eV as the particle moves from postition A to position B. The electric potential at A is -55.0V, and the electric potential at B is +27.0 V. Determine the charge of the particle. Include the algebraic sign (+ or -) with your answer.
