Hurry And here's your shmoop too sure brought to you

00:05

by robots And since they'll probably take over the planet

00:08

eventually we just like to take this opportunity to say

00:10

that we love robots here It's come up We think

00:14

they're just great A robot family drops a metal conducting

00:20

sponge into a sink full of electrons The robot son

00:23

is washing the pile of dirty dishes on the counter

00:26

he reaches for the first dirty dish which is neutrally

00:29

charged What will happen is the robot son moves the

00:32

sponge near but doesn't touch the plate And here the

00:36

potential answers like neutral and help you play become negatively

00:40

trying electrons from funny All right this robot family doesn't

00:44

own a dishwasher all right And we hope that robby

00:48

the robot here is wearing gloves to wash these dishes

00:51

Those electrons can't be good for the metallic skin The

00:54

most crucial part of this question is that the sponge

00:56

and the plate don't actually touch They did touch Then

01:00

electrons might jump from the sponge to the plate but

01:03

without any physical contact those electrons are staying put So

01:06

what does that mean for our question Well if the

01:10

electrons are staying put there's no way C is the

01:12

correct choice until science find subatomic size pogo sticks Electrons

01:17

aren't leaping onto any neutral dishes and the same goes

01:21

for answer d the electrons can redistribute themselves within the

01:25

system because there is no system They're not touching and

01:28

answer B is out to a neutral object Can't just

01:31

go around willy nilly making other objects neutral That violates

01:34

the law of conservation of charge So the correct answer

01:39

is a the plate is going to just sit there

01:42

like a well an empty plate being all relaxed in

01:46

neutral We aspire to such a zen like state be

01:49

neutral become be the plate Don't be scared of robots 00:01:52.142 --> [endTime] taking over the world
