Two circular coils X and Y, having equal number of turns and carrying currents in the same sense, subtend same solid angle at point O. If the smaller coil X is midway between O and Y and if we represent the magnetic induction due to bigger coil Y at O as `B_y` and the due to smaller coil X at O as `B_x`,then find the ratio `B_x//B_y`.

A

`(B_(y))/(B_(x))=1`

B

`(b_(y))/(B_(x))=2`

C

`(B_(y))/(B_(x))=(1)/(2)`

D

`(B_(y))/(B_(x))=(1)/(4)`
