Two identical long conducting wires AOB ...

Two identical long conducting wires AOB and Cod are placed at right angles to each other, with one above other such that O is their common point for the two. The wires carry `I_(1) and I_(2)` currents, respectively. Points P is lying at distance d form O along a direction perpendicular to the plane containing the wires. The magnetic field at the point P will be

A

`(mu_(0))/(2pid)((I_(1))/(I_(2)))`

B

`(mu_(0))/(2pid)(I_(1)+I_(2))`

C

`(mu_(0))/(2pid)(I_(1)^(2)-I_(2)^(2))`

D

`(mu_(0))/(2pid)(I_(1)^(2)+I_(2)^(2))^(2)`
