Which Rod Transfers More Charge to a Metal Ball?

[duoheer]

Let's say we have a charged plastic rod and a neutral metal ball, and a charged metal rod and neutral metal ball, which rod can transfer more charge onto the metal ball? Or metal ball onto the rod (if the rods are positive)
Thank you

How are you making them interact? Just touching one point of the rod to the ball, in either case, or in some other way?

for your question. In this scenario, the charged plastic rod and charged metal rod both have excess charge, while the neutral metal balls do not have any excess charge. When a charged object comes into contact with a neutral object, the excess charge can be transferred to the neutral object, making it charged as well. This process is known as charging by contact.

In terms of which rod can transfer more charge onto the metal ball, it ultimately depends on the amount of excess charge on each rod. If the charged plastic rod has a higher magnitude of excess charge compared to the charged metal rod, then it will be able to transfer more charge onto the metal ball. On the other hand, if the charged metal rod has a higher magnitude of excess charge, it will be able to transfer more charge onto the metal ball.

Similarly, when considering the transfer of charge from the metal ball onto the rods (assuming the rods are positive), the same principle applies. The metal ball will transfer more charge onto the rod with a higher magnitude of excess charge.

It is important to note that the type of charge (positive or negative) on the rods does not affect the amount of charge that can be transferred onto the metal ball. The amount of excess charge is the determining factor.

In conclusion, the amount of excess charge on the rods will determine which rod can transfer more charge onto the metal ball or vice versa. This is a fundamental concept in electrostatics and can be further explored through experiments and calculations. I hope this helps clarify your question.
