Magnetic Field Due To Current Carrying Solenoid

An infinetely long conductor PQR is bent tor form a right angle as shown in Fig. A current I flows through PQR. The magnetic field due to this current carrying conductor at the point M is B_1 . Now, another infinitely long straight conductor QS, is connected at Q so that the current is 1/2I in QR as well as in QS, is the current in PQ remaininig unchanged. The magnetic field at M is now B_2 . The ratio B_1//B_2 is given by
