Imagine if you have two charged plates which have the same magnitude but opposite in charges.
If you place an uncharged object near of the positive plate what will happen?
I don't think it depends on equations
The Attempt at a Solution
Okay, so If you rub a balloon with your hair, it will gain a negative charge. If you place that balloon really close to really small pieces of paper, It will attract them because the balloon will repel the electrons away from it and the protons don't move so the object will be polarized ( I am pretty sure that I can't say that this effect split the electrons and protons into two different sides equally , can I?)
So the negative charge will attract the protons more than it will attract the electrons because the protons are much closer to it than the electrons. So that will result in a net force to the balloon.
Now back to the question
If I place the uncharged object near the positive plate, the opposite of the above will happen. However, The negative charged plate will attract the protons and the positive plate will repel the protons in the same direction
and the same thing will happen to the electrons but opposite.
The answer in my book was that the uncharged object won't move. But what I think if we assume that it won't move we are just saying that the (distance) between the repelled electrons and attracted protons is just zero which proves that the first idea is wrong.
So, What is really happening here?
Thanks in advance.
