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

A conducting rod of mass 200 gm and length 10 cm can slide without friction on two long an induced current is developed in it 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.
