Let's solve the given quotient.
00:02
There are three point charges.
00:05
Plus of q here.
00:10
Another point charge that is plus of q.
00:12
And here is a negative of.
00:16
The charge value is one micro column.
00:19
Here is one micro column.
00:21
Here is one micro column.
00:24
The fbt for this is.
00:29
Here is a force f.
00:35
And due to the negative point charge.
00:38
Here is the force f.
00:44
This angle is 60 degree.
00:47
So this angle is 30 degree.
00:53
So the x and y components are given as.
00:57
Here is f cos 60 degree.
01:02
Here f sin of 60 degree.
01:08
Here f cos 30 degree.
01:12
Here f sin 30 degree.
01:18
The distance between the two point charges are 2 nanometer.
01:21
2 nanometer.
01:25
Now the force f is given as.
01:36
So the distance that is.
01:41
Here the horizontal component.
01:53
That is horizontal component.
02:02
Del of f is the total force in the horizontal component.
02:06
Here it is f cos 60 degree.
02:09
In the opposite direction f sin 60.
02:11
So we can say f cos 30 degree.
02:15
Minus of f sin 60 degree.
02:19
Therefore, it is f root 3 by 2.
02:23
Minus of f root 3 by 2.
02:26
Similarly the vertical component...
