Pls give me instructions to solve this question

The size of the loop is L : 0.3m, W : 0.02m, the loop carries a current of [Imp : 10A, and is a distance d = 2 X 10'3m from the wire. lfthe magnitude of the force on the loop due to the magnetic eld of the long wire is F3 : 3 X lO'SN, what is the current in the long wire
