Two circular coils A and B with their centres lying on the same axis have differents in the same sence. The coil B lies exacity midway between coil A and the point P. The magnetic field at point P due to coils A and B is `B_(1)` and `B_(2)` respectively.
A. `B_(1) gtB_(2)`
B. `B_(1) ltB_(2)`
C. `(B_(1))/(B_(2))=2`
D. `(B_(1))/(B_(2))=(1)/(2)`
