a.neither of them is correct
b. Zach's statement is not correct, since do not know where the objects started and can't be sure if they pass each other.
c. Victoria's statement is not correct as the objects have the opposite accelerations, however free-falling objects should have the same downward acceleration

Why is Victoria's statement wrong? Check all that apply Victoria's statement is not correct as the objects both should have been thrown either upward or downward
Answer:. Victoria's statement is not correct as the objects have the opposite accelerations, however free-falling objects should have the same downward acceleration gGraph
My explanation further from the graph will be that there are opposite bodies, one is accelerating with time , why the other is decelerating with time.
Answer:
ball will oscillate in between the plates
Explanation:
The metallic coated styrofoam lowered in between two large metal plates, a large potential difference V is kept between the two plates, will experience a force of repulsion ( because both plates and balls will have similar kind of charges and like charges repel each other) from the opposite plates.
If we consider d as the distance between the plates, E as electric field because of Potential difference V. Then force F experience by the ball will be
where q be the total charge on the metallic coated ball.
clearly, since, both the plates will repel the ball in opposite directions, hence ball will be in oscillate in between the plates.
