A proton is moving toward a stationary charged particle. Which statement correctly describes an energy change that could occur as the particles get closer?

AKinetic energy will be converted into electric potential energy if the stationary particle is positive.

BKinetic energy will be converted into electric potential energy if the stationary particle is negative.

CElectric potential energy will be converted into kinetic energy if the stationary particle is positive.

DElectric potential energy will be converted into thermal energy if the stationary particle is negative.
