Answer to Problem 85P
The magnetic field at point R is
Explanation of Solution
The diagram for the magnetic field is depicted in figure 1:
The vertical component of the two fields will cancel each other and the horizontal component will added up.
Write the equation of net magnetic field.
Here,
Write the equation magnetic field due to left,
Here,
Write the equation magnetic field due to right,
Here,
Write the equation of the distance,
Here,
Write the equation of the distance,
Write the equation of the angle.
Rewrite the expression from equation (I)
Conclusion:
Substitute
The direction of the magnetic field is directed to the right.
Thus, the magnetic field at point R is
