Figure shows a conducting disc rotating about its axis in a perpendicular uniform and constant magnetic field B. A resistor of resistance R is connected between the centre and the rim. The radius of the disc is 5.0 cm, angular speed `omega=40 rad//s, B=0.10 T \" and \" R=1 Omega`. The current through the resistor is
