A positively charged light metal ball is suspended between two oppositely charged metal plates on an insulating thread as shown below. After being charged once, the plates are disconnected from the battery. Describe the behavior of the ball.
Thank you so much!
Could you please describe the behavior of the ball that is centered between the two plates that are not attached. The brackets represent the plates and the parenthesis represent the hanging ball on an insulator thread.

Thank you so so much!
The ball goes from plate to plate, until they are discharged. I will be happy to critique your explanation of this.
Hi bobpursley. Thank you very much for the starting point. Here goes my guess at the explanation:
The positive ball would go first to the negatively charged plate. After which, it would hold a more negative charge. Due to the negative charge, it would travel towards the positive plate. Thereby, it would transfer negative electrons to the positive plate. Leaving the positive plate, it would be more positive and be drawn towards the negative plate once more. In doing so, it would transfer positive protons to the negative plate. After which, it would hold more negative electrons and be drawn towards the positive plate once more. The process would continue until the once-positive and once-negative became neutral (and were discharged. Additionally, the ball hanging on the insulator thread would also be neutral (and discharged).
Thank you so much for the help! Please let me know if this explanation is correct.
Based on the given scenario, the positively charged light metal ball is suspended between two oppositely charged metal plates on an insulating thread. After being charged once, the plates are disconnected from the battery. To describe the behavior of the ball, we can consider the interactions between the charges.
Initially, when the ball is charged and placed between the plates, it experiences a force due to the electric field created by the charged plates. The positive charge on the ball will be attracted to the negatively charged plate and repelled by the positively charged plate. This attraction and repulsion will cause the ball to move towards the negatively charged plate and away from the positively charged plate.
Once the plates are disconnected from the battery, the electric field between them will disperse. However, the charges on the plates and the ball remain. Since the ball is positively charged, it will still be repelled by the positively charged plate and attracted to the negatively charged plate. As a result, the ball will continue to move towards the negatively charged plate.
The behavior of the ball will depend on various factors such as the strength of the charges, the distance between the plates, and the mass of the ball. If the charges are strong and the distance between the plates is small, the ball may move quickly towards the negatively charged plate. On the other hand, if the charges are weak and the distance between the plates is large, the ball may exhibit slower or negligible movement.
Overall, the behavior of the positively charged ball in this scenario will be to move towards the negatively charged plate until it reaches a stable position or equilibrium.
