A conducting rod of mass 200 gm and length 10 cm can slide without friction on two long, horizontal rails. A uniform magnetic field of magnitude 5 m T exists in the region as shown. A source S is used to maintain a constant current 2 A through the rod. If motion of the rod starts from the rest, find its speed (in cm/s) after 10 s from the start of the motion

In Fig. ABCD is a fixed smooth conducting frame in horizontal plane. 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)`
