A rod of mass m and resistance R slides without friction in a horizontal plane, moving on parallel rails as shown in figure. The rails are separated by a distance d. A battery that maintains a constant emf ε is connected between the rails, and a constant magnetic field B is directed out of the page. Assuming the rod starts from rest at time t = 0, find its velocity in terms of time t, ε, B, d, m, and R.
