In this question we have given the odd chart which is placed at the corner of the squires and the distance between them is 2 cm each so we need to find the direction and obviously magnitude of the electric wheel.
00:14
I mean there's a direction with the vector.
00:16
So a very simple question what we need to do over here is first of all we will draw the diagram right.
00:21
So say this is like this is one let you draw it better.
00:35
Say this is a square like this is a square like this and again this is the other side let me draw it better or just let me draw by the pin itself so this is the square okay figure might be some not what look like that one but see this is just a square okay and now what we need to do is over here this is q charge q1 charge over here this is q2 charge this is q3 charge q4 charge sorry this over here q4 charge this is q5 charge, q6 charge and q7 charge and q8 charge, okay? now we need to write the magnitude of each one.
01:42
So q1 equals to 3e plus 3e, obviously q2 equals to e, q3 equals to minus of 5u, q4 equals to minus of 2e, q5 equals to plus of 3e, and q6 equals to plus of e, and q7 equals to minus of 5e, q8 equals to e.
02:02
So see, very simple question, each have a distance of d, which is equals to 2 centimeter, 2 centimeter.
02:08
So we need to find the magnitude and direction at the center, okay? so very simple question, electric field due to this q2 will be upper direction, in downward direction and this will be upward direction.
02:18
And obviously the distance between these are d, so this will be d.
02:21
So see, we know that the electric field will be same for this one and this one.
02:26
Why charges is same and distance is same.
02:29
So same and opposite direction...
