A metallic square loop ABCD of size 15 cm and resistance 1.0 Ω is moved at a uniform velocity of v m/s, in a uniform magnetic field of 2 T, the field lines being normal to the plane of the paper. The loop is connected to an electrical network of resistors, each of resistance 2 Ω. Calculate the speed of the loop, for which 2 mA current flows in the loop.
