A long horizontal wire 'A' carries a current of 50 Amp. It is rigidly fixed. Another small wire 'B' is placed just above and parallel to 'A'. The weight of wire-B per unit length is `75X10^(-3)` Newton/meter and carries a current of 25 Amp. Find the position of wire B from A so that wire B remains suspended due to magnetic repulsion. Also indicate the direction of current in B w.r.t. to A.
Options:
(a) `1/2xx10^(-2)` m; in sume direction
(b) `1/3xx10^(-2)` m; in mutually opposite direction
(c) `1/4xx10^(-2)` m; in same direction
(d) `1/5xx10^(-2)` m ; in mutally opposite direction
