Thank you We sneak and here's your shmoop du jour
- 00:05
brought to you by conducting And we're talking about electricity
- 00:08
Not think i waving a stick in front of the
- 00:10
orchestra No conducting sphere with a radius of five meters
- 00:15
is charged with a charge of twenty cool ums what's

- 00:19
the magnitude of the electric field three meters from the
- 00:22
centre of the sphere sign here Potential answers radiating electricity
- 00:28
All right well this one might seem a little tricky
- 00:30
Sorry but we like to mix it up a little
- 00:31
sometimes Yeah zig where we should go back slap you
- 00:34
with some peanut butter when you're thinking jelly You know
- 00:37
that's what we're saying we're trying to make happen and
- 00:38
just go with it All right So we have this
- 00:40
severe it's pretty big ten meters across to be exact
- 00:44
The question asked about the charge three meters from the
- 00:47
centre of the sphere That means we're talking about what's
- 00:50
going on inside the sphere Well inside this fear All
- 00:53
the charged particles are running away from each other That
- 00:57
that's because particles with like charges repel each other So
- 01:01
the charged particles try to make a run for it
- 01:03
We only get us faras the edge of the sphere
- 01:05
of course but they're not hanging out in the middle
- 01:08
Three meters in it's all relaxed in neutral and kind
- 01:12
of chill there's no charge at all The correct answer
- 01:15
is a that's it and we might like classical music
- 01:18
More of the orchestra conductor didn t use electricity You 00:01:21.263 --> [endTime] definitely get the whole thing and more charged up
