A current I is flowing along an infinite, straight wire, in the positive Z-direction and the same current is flowing along a similar parallel wire 5 m apart, in the negative Z- direction. A point P is at a perpendicular distance 3 m from the first wire and 4 m from the second. What will be magnitude of the magnetic field `vecB` at P?

A

`5/12 (mu_(0)I/pi)`

B

`7/24(mu_(0)I)/pi`

C

`5/24 (mu_(0)I/pi)`

D

`25/288 (mu_(0)I/pi)`
