Two identical conducting wires `AOB and COD` are placed at right angles to each other. The wire `AOB` carries an electric current `I_(1) and COD` carries a current `I_(2)`. The magnetic field on a point lying at a distance `d` from O, in a direction perpendicular to the plane of the wires `AOB and COD`, will be given by

Options

A. `(mu_(0))/(2 pi d)((I_(1))/(I_(2)))`
B. `(mu_(0))/(2 pi d)(I_(1) + I_(2))`
C. `(mu_(0))/(2 pi d)(I_(1)^(2) - I_(2)^(2))`
D. `(mu_(0))/(2 pi d)(I_(1)^(2)+I_(2)^(2))^(1//2)`

Answer

D
