QUESTION
A proton is initially at rest at a point where the potential is 461 V. Some time later the proton is at a point where the potential is 192 V.
A proton is initially at rest at a point where the potential is 461 V. Some time later the proton is at a point where the potential is 192 V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy?
