T is bulb of power 100 W,P is a smooth pulley and OQ is a conducting rod. Neglect the self-inductance of the loop and resistance of any part other than the bulb. The mass M is moving down with constant velocity 10 m/s. Bulb lights at its rated power due to induced emf in the loop due to earth’s magnetic field. Find the mass M (in kg) of teh block. (g = 10 ms^(2)`

an induced current is developed in it In Fig. ABCD is a fixed smooth conducting frame in horizontal plane. T is bulb of power 100 W Some magnetic flux is changed from a coil of resistance 10Ω. As a result which varies with time as shown in figure. Find the magnitude of the change in flux through the coil in weber.
