4. A positively charged particle is placed halfway between the plates of a charged parallel plate capacitor, which is hooked up to a battery. What statements about this physical system are true? Circle all answers that apply. (A) The particle would travel in a straight line until it reaches the positive plate. (B) The particle would travel in a spiral until it reaches the positive plate. (C) The particle would travel in a straight line until it reaches the negative plate. (D) Increasing the plate spacing would weaken the capacitor's electric field. (E) Increasing the plate spacing would strengthen the capacitor's electric field. (F) Increasing the plate spacing would not change the capacitor's electric field.
