A rod of length 1 1m and resistance R 100 is being pulled with a constant velocity of 4m s towards right At time 1 0 the rod is 1m away from left end The magnetic field is B 1 31 T Find work done in J by the external agent to move the rod with constant velocity for first 5sec the rest of circuit is resistance less Neglect friction 4 point
