At the three problems, fifty six is, according to coolum slaw ranked interaction between charged particles from lowest to highest and potential energy.
00:08
Let's remind ourselves what the equation is for cooling.
00:12
Okay, which is the constant times in charge of two different particles will call one one and the other two divided by the distance.
00:21
Those product was aaron part square.
00:25
The first one were given.
00:27
It is a positive one charge a negative one charge that are one hundred people meters apart.
00:34
So this will be our kyu won.
00:37
This will make you too.
00:39
And this will be our our for me.
00:45
Let's do it in a different company.
00:50
We have positive too minus one at one hundred people meters apart for sea.
01:01
We have positive to positive one another positive one at one hundred people meters apart.
01:09
And for d, we have positive one and negative one at two hundred people meters apart.
01:17
So i'm gonna put these into the equation and see what chances we kid starting with a we'll have k times one times negative one divided by one hundred square, don't you? zero negative zero point zero zero zero one times k if we do the next one.
01:55
We're going to do it in red.
02:03
It's gonna be okay.
02:06
Times two times.
02:08
Negative one.
02:10
What about it? by one hundred square.
02:16
So if you put this into the equation, breguet negative.
02:20
Zero point zero zero two.
02:24
Okay, now make sure that this looks more like a zero.
02:35
There we go...
