A student makes the claim that the space around a charged particle will exert a force on any other charged particle that is placed within this space. If an object is placed between two charged metal plates, one plate that is positively charged and one plate that is negatively charged, which argument BEST supports the student's claim?

Question

A student makes the claim that the space around a charged particle will exert a force on any other charged particle that is placed within this space. If an object is placed between two charged metal plates, one plate that is positively charged and one plate that is negatively charged, which argument BEST supports the student's claim?

Responses

A neutrally-charged object will move toward the negative plate.
A neutrally-charged object will move toward the negative plate.

An object with a positive charge will move toward the negative plate.
An object with a positive charge will move toward the negative plate.

A neutrally-charged object will move toward the positive plate.
A neutrally-charged object will move toward the positive plate.

An object with a negative charge will remain stationary between the plates.

Answer 1

An object with a positive charge will move toward the negative plate. This supports the student's claim that a charged particle will experience a force when placed within the space around another charged particle. The positively charged plate will create an electric field that will exert a force on a positively charged object, causing it to move toward the negatively charged plate. This movement is evidence that the charged particle is experiencing a force due to the electric field created by the charged metal plates.
