Two large parallel metal plates X and Y are situated in a vacuum as shown. [Diagram] Plates X and Y carry equal and opposite charges. What happens to the force on a positively charged particle as it moves from plate X to plate Y?
AIt decreases because the positively charged particle is moving away from the positively charged plate.
BIt decreases because the positively charged particle is moving in the direction of the electric field between the plates.
CIt increases because the positively charged particle is moving closer to a negatively charged plate.
DIt remains constant because the positively charged particle is in the uniform electric field between the plates.
