the radius of coil P = R
the radius of coil Q = 2R
Are both coils are lying in the same plane and their centres are coinciding.
As the director of the current is opposite the magnetic field are also opposite.
The resultant direction of the magnetic field is in the direction of the magnetic field produced by coil P.
