In the question, there are multiple parts.
00:05
In first part of the question, we have to find current i1, then net magnetic field, then individual forces.
00:13
According to question, diagram is like this, in which there are two parallel conductors which carrying the current i1 and i2.
00:21
Distance between two conductor is d and all remaining values are given in the question.
00:26
In first part of the question, we have to find current i1.
00:35
We will use magnetic field formula at point c.
00:40
Let us consider at point c magnetic field mu not i1 divided by 2 pi d plus which is total distance 5 .78.
01:03
It is magnetic field at point c due to current carrying conductor i1 minus magnetic field due to current carrying conductor i2 will be mu not i2 2 pi and distance of point c which is 5 .78.
01:23
It will be 0.
01:27
Now from this equation we will get i1 divided by d plus 5 .78 equal to i2 divided by 5 .78 now from this equation i2 is given to us hence i1 will be 33 .38 ampere.
02:03
So our final answer is i1 equal to 33 .38 amper.
02:11
Now in second part of the question we have to find b equal to in second part of the question that is b we have to find b we have to find net magnetic field at point a that is net magnetic field at point a so at magnetic field at point a magnetic field will be additive in nature so b net will be equal to mu not i1 divided by 2 pi d by 2 plus mu not i 2 divided by 2 2 pi d by 2...
