A charge moves a distance of 2.3 cm in thedirection of a uniform electric field havinga magnitude of 239 N/C. The electricalpotential energy of the charge decreases by72.3544 × 10−19 J as it moves.Find the magnitude of the charge on themoving particle. (Hint: The electrical poten-tial energy depends on the distance moved inthe direction of the field.)Answer in units of C.
