Hi, here in this given problem, the two charged particles, q1 and q2, are kept at the vertices of an equilateral triangle.
00:12
Sorry, a right angled triangle.
00:15
This is the right angle triangle, charge q2, charge q1, the gap between them 40 centimeter.
00:22
And here, this perpendicular side of the right triangle, that is 30 centimeter.
00:27
There is a point m at which we have to find net.
00:31
Electric field due to these two charges q1 and q2.
00:34
So using pathogorous theorem, this hypotenuse is calculated to be equal to 50 centimeters.
00:41
So as we know, electric field goes away from the positive charge.
00:45
This is positive.
00:46
This is negative.
00:47
So electric field will be going away from the positive charge.
00:52
This is symbolized as e at m due to charge to em2.
00:59
And this is towards the negative charge.
01:02
It is symbolized as e at m2 .1.
01:07
So the net electric field will be found using parallelogram law of vector addition.
01:14
This will be a net which we have to find...
