A long horizontal wire `P` carries of `50 A`. It is rigidly fixed. Another fine wire `Q` is placed directly above and parallel to `P`. The wieght of wire `Q` is `0.075 N//m` and carries a current of `25 A`. Find the position of wire `Q` from `P` so that the wire `Q` remains suspended due to magnetic repulsion.
