Hi in the given problem, the two straight parallel current carrying conductors are yet such that they are perpendicular. The plane of paper in the wire, one the first conductor. The current is coming out of the Pelino paper and the direction of current in the conductor too. That is not given in the beginning gap between them. He's given us and centimetre. Then an observation point B is at a perpendicular by sector of this line joining their book conductors, such that if we join across sections of these two conductors with this observation point angle between these two lines is given as 90 degree. So here this is 90 degree. This is perpendicular perpendicular by sectors. So each of these two angles will be 45 degree each. This is 45 this is nineties. So clearly this angle here will also be 45 degrees. This distance will be half of 10, means five centimeter. You know, this strangle will also be and I Socialist right angle triangle. And see if this is why this distance will also be filed. So finally we can see if you consider this wire to be situated at point you this wire to be situated at point R. Then PQ is equal to P. R. And that is equal to square root of 50 centimetre. This is five, this is five. Then using pythagoras. Tehran square root of every centimeter will be this hyper tennis. No, in the first part of the problem if good on in via to is outward out of the plane of paper then using right and come rule the directions of magnetic feels the one magnetic field due to the current environment and B two magnetic field you to quarantine wire to at point B will be as shown in the figure. So using their right and thumb rule considering the current environment which is coming out of a plane of paper the direction of this magnetic field that point he will be like this. This is the one and you too the current environment which is also coming out of the plane of paper. That will be yes this is B. Two. And using the symmetry of these angers angle between these two magnetic fields is also equal to 90 degrees. Now magnitudes of these two magnetic fields will be equal because the currents in both of the virus is same and understand speak U. Is equal to P. R. And that magnitude will will be given by mu note by four by into two. I buy. Oh were this distance square root of 50 centimeters is equal to our Now plugging in all known values here for Munich upon four by the standish par minus seven islam meter perimeter here multiplied by two times of current and current here It's given us 100 ampere in both of the wires and then the distance which is the square root of 50 centimeter or it's quite out of 15 to 10 days par minus two m. In Tesla disagree measure. So finally these two magnetic fears comes out to be four into 10 par minus four. Invited by rubio S la. So net magnetic field having angle 90 degree between them. If we use parallel ground law of tradition, this will be the net magnetic field a long negative by access. So again using pythagoras here. Um, this will be given there as a square root of even his car. Class B two square as both the magnetic fields are same. So we can say in place of B two, we can use Beaven square, it will be twice or even square having a square root. Or we can say this is be even in two. Finally, we can say this is foreign to 10 for minus four, divided by two, multiplied by two. Tesla. Or in vector form we can see this is as it is a long minus Y. X. And so sorry, minus X. X. And so we can write it like minus pour into a 10 for minus four. That's la Oh you get Which is the answer for the first part of this problem? No, in the second part of the problem, if we reverse the direction of current in wire to so if current in wire to yes in world into the plane of paper, then the direction of magnetic reed due to this current will be changed if you don't this diagram again here again, this is why one carrying current in outward direction. But this is why getting currently inward direction. It says perpendicular by sector again, this is the observation point at which now we have to find net magnetic field. So here the direction of magnetic will do to buy one. That will be same as we have done in the first part of the problem, going like this be one, but now the direction of the two that will be like this as the current and the distances are still the same. So magnitude of these two magnetic fields will be still. The scene means four into tended bar minus four. By route to Tesla. Again, the angle between them 90 degree. So if we apply parallelogram law of tradition, this time the net magnetic will it will be having same magnitude means physical too. The one in two square root of two Tesla for direction it is vertically up means along positive Y axis. So we can say this is yes, 4.0 into tended bar minus four. Yes La G. Yeah. Which is the answer for the second part of this problem. Thank you.
