Due to battery current I (= E/R)the rod in the magnetic field B will experience a force
...(i)
which will accelerate the rod. However, due to motion of the rod in the field, an emf
will be induced in it. Due to this induced emf, the induced current 
will result in a force
...(ii)
which will oppose the motion of the rod as shown in Fig. So the equation of motion of the rod will be
