Moving Charges And Magnetism

A long horizontal wire \(\mathrm{P}\) carries current of \(50 \mathrm{~A}\) from left to right. It is rigidly fixed. Another fine wire \(\mathrm{Q}\) is placed directly above and parallel to \(\mathrm{P}\). The mass of the wire is '\(\mathrm{m}\)' \(\mathrm{kg}\) and carries a current of '\(\mathrm{I}\)' A. The direction of current in \(\mathrm{Q}\) and position of wire \(\mathrm{Q}\) from \(\mathrm{P}\) so that the wire \(\mathrm{Q}\) remains suspended are
