Final answer:
B. Yes, it is possible for a particle to move in a direction of increasing electric potential while its electric potential energy decreases.
Step-by-step explanation:
Yes, it is possible for a particle to move in a direction of increasing electric potential while its electric potential energy decreases. The change in electric potential energy depends on the charge and the direction of the electric field.
For example, if a negative charge moves towards a region of higher potential, its electric potential energy decreases. This is because the electric field and the force on the negative charge are in opposite directions. As the charge moves, the work done by the electric force decreases its potential energy and increases its kinetic energy.
Another scenario is when a positive charge moves towards a region of higher potential. In this case, the electric potential energy of the positive charge increases as it moves closer to the source of the electric field. The positive charge is accelerated by the electric force, which does work on the charge, increasing its potential energy.
