A frame PQRS is placed in a region where magnetic field B is present, as shown in the figure. A rod of length 2 m moves with a constant velocity 25 m/s and the strength of the magnetic field inside the plane of paper is 0.1 T. If the resistance of the rod is 10 Ω and the resistance of the frame is negligible, then calculate the power spent in this process |
