4. Two semi-infinite parallel metal rails have one sides connected through a battery of constant emf ɛ and a and resistor of resistance R (Fig. 2). R A straight rod PQ of mass m and length I, is x B x F placed on and perpendicular to the rails. The setup is placed in a uniform magnetic field B pointing into the page. At time t=0, the rod begins to move from rest smoothly over the rails S to the right. Fig. 2 (a) Express the emf induced in the circuit when the rod is moving at a speed v. (b) Hence find the current I in the rod in terms of ɛ , l, B, v and R.
