A current carrying rectangular loop \(P Q R S\) is made of uniform wire. The length \(PR = QS = 5\;cm\) and \(PQ = RS = 100\;cm\). If ammeter current reading changes from \(I\) to 2 \(I\), the ratio of magnetic forces per unit length on the wire \(P Q\) due to wire \(R S\) in the two cases respectively \(\left(f_{P Q}^{I}: f_{P Q}^{2 I}\right)\) is
