Each of two long parallel wires carries a constant current `i` along the same direction . The wires are separated by a distance `2I`. The magnitude of resultant magnetic induction in the symmetric plane of this system located between the wires at a distance `R` from each wire will be
A. `(mu_(0)i)/(piR)`
B. zero
C. `(mu_(0)i)/(pisqrt(R^(2)-l^(2)))`
D. `(mu_(0)i)/(piR)sqrt(1-(l^(2))/(R^(2)))`
