In this problem, it is asked that point charges q1 equal to plus 4 muci, that is microculum and q2 equal to plus 2 microcholum are placed at the opposite coroners of a triangle, sorry, or of a rectangle as shown in the figure.
00:31
What is the potential at the point b due to these charges? so we need to find the potential l at b.
00:40
So whatever is connected to b, we will find potential for it, right? so potential is basically we can say that the potential at point b is given by vb, let us say.
01:05
Let us say the potential at b is vb is given by kq1 by r1.
01:12
So this is formula called it that this charge and k is constant r is the distance between the charge and the point we are calculating for.
01:23
So this is k q2 by r2.
01:26
So here we can say that there are two charges attached to it.
01:32
So we can say r1 equals to distance between q1 and point b...
