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?

An object with a negative charge will remain stationary between the plates.
A neutrally-charged object 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.

Answer 1

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

Reason: the electric field between the plates points from the positive plate to the negative plate, so a positive charge feels a force in that direction (opposite charges attract).
