Question

describe what happens to paper dots when you place a rubbed plastic ruler and plastic foam cup near them. Include the terms electric charge and electric force.

Answer 1

Is this related to the triboelectric charge?

You can say that when the plastic rubber ruler and plastic foam cup are in contact, it forms a relatively neutral electric field, and when rubbing them and then separating the two away, it forms an electric charge.

Answer 2

Yes it indeed is. Yes upon experimenting i did find that they both attract the bits of paper how i was unsure how it related to the electric force and electric charge. what is the difference between them ?

Answer 3

or in other words how would they relate to the paper attaching to them in the terms of electric force and electric charge .

Answer 4

An electric charge is analogous to a force from mechanics. An electric field is analogous to a body.

There are several charges that create a whole field

Answer 5

is electric field the same as electric force in your comment above ^?

Answer 6

Oh wait sorry I read your question wrong.

Electric force and electric charge kind of go hand-in-hand. Electric charge is the source, it is the attribute of an object that induces an electric force.

Answer 7

Its okay, how would that then relate to the cup and ruler. Im still quite confused , sorry

You could say this:

After contact electrification of the two objects, the electric charges worked to create an electric force of attraction.

Answer 9

Sorry I've got to go right now. If you still have a doubt, @DuarteME might be able to help you.

Answer 10

Okay, thank you so much for you help though! Have a good rest of your evening
