A rectangular loop of dimensions `l` & `w` and resistance `R` moves with constant velocity `V` to the right as shown in the figure. It continues to move with same speed through a region containing a uniform magnetic field B directed into the plane of the paper & extending a distance `3W`.
Sketch the flux, induced emf & external force acting on the loop as a function of the distance.
