A movig particle encounters an external electric field that, Ask an Expert

Academics

A movig particle encounters an external electric field that decreases its kinetic energy from 9380 eV to 7310 eV as the particle moves from position A to position B. The electric potential at A is -66.0 V, and that at Bis +28.0 V. Determine the charge of the particle. Include thealgebraic sign (+ or -) with your answer.
