Question

Help please

Answer 1

excess electrons

Answer 2

electrons are negative, protons are positive, neutrons are neutral/no charge

Answer 3

induction is charging by bringing another charged object close, but not touching
conduction is charging by direct contact.
pressure has nothing to do with this.
triboelectricity is charging something by friction (like rubbing your feet on carpet)

What do you think this is?

Answer 4

Induction sounds right

Answer 5

What if induction was happening with a negatively charged object? What would happen then?
@funscience

Answer 6

I think induction

Answer 7

can you be more specific? Describe the situation. Induction can happen with positive or negative.

Answer 8

I think it's the first one

Answer 9

Remember, electrons (negative charges) are the only charges that are able to move. Protons which are positive, cannot move. When something is negative, it just means that it has too many electrons. When something is positive, we have too few electrons.

Answer 10

The induction happens, when, for example a neutral sphere is in front of a charged sphere:

Answer 11

So it's either B or D

Answer 12

yes!, Since only electrons can move into objects

Answer 13

under external electic field, of course

Answer 14

I think it's B

Answer 15

Is that right? @funscience

Answer 16

we have to specify that the negative charge wiil appear on the surface closest to the charged object, whereas the positively charge will appear on the surface farest with respect the charged object

Answer 17

In that sense only option B is correct. Nevertheless both of type of charge will appear on the surface of the neutral object

Answer 18

That makes sense! Thank you both!

Answer 19

of course I'm referring to my drawing above

Answer 20

Thank you!

Answer 21

It's B
