In this problem, we are given that there are three point charges.
00:04
And these three point charges, they are placed on the x -axis.
00:09
So let's say these are the point charges here.
00:12
And the first charge, which is two microculum charge, this is placed at the origin.
00:18
So this x is zero.
00:20
At this point, two microculem charge is present.
00:23
Another charge is present at x is equal to 40 centimeter.
00:27
And this charge here is minus three microculum charge and the third charge here it's placed at 120 centimeter from the origin and this is minus 5 microculum charge and we are required to determine the force on the minus 3 microculum charge as well as on minus 5 microculum charge so first we have to get the force on this minus three microculum charge, let's say it is f1 and the force on minus 5 microculum charge.
01:07
Let's take it as f2.
01:09
So we will use this formula according to coulomb slot to get the force.
01:13
And k here is columns constant.
01:15
We have the value here which we can use...
