Hello, in the question we have given a minus 25 into 10 raised to minus 6 coulomb charge.
00:08
So let us call this charge as q1.
00:10
So that is given to be minus 25 into 10 raised to minus 6 coulombs experiences a 16 .5 newton force.
00:20
So this force is given that is 16 .5 newtons.
00:26
So repulsive force, so they have mentioned repulsive, so direction is included in this force.
00:33
Further, due to minus 68 into 10 raised to minus 6 charge, so let us call this as q2, that is minus of 68 into 10 raised to minus 6 coulombs.
00:48
So how far apart they are two charges? so we have to find out the distance between them.
00:56
So let us say the distance between the two charges is r.
01:00
So we will use the coulomb's law over here.
01:09
So according to the coulomb's law, the force between the two charges is given by f is equals to ka q1.
01:16
So we have written capital.
01:19
So q1 q2 divided by r.
01:23
So r square, sorry.
01:27
So from here, we can just replace r square.
01:30
So r will be equal to square root of ka q1 q2 divided by this f will come over here.
01:41
So this will be the distance of separation between them.
01:46
So now let us plug over here the values...
