73. Flat closed loop area S = 100 cm 2 and the resistance R = 5,0 Ohm is located in a uniform magnetic field of H = 10 kA / m perpendicular to the lines of force. When rotation circuit by an angle α (α <90 °) around an axis lying in the plane of the coil, the count of the ballistic galvanometer connected to the circuit constituted Q = 12,5 SCLC. Determine the rotation angle α.
