Two straight conducting rails form a right angle where their ends are joined. A conducting bar in contact with the rails starts at the vertex at time t = 0 and moves with constant velocity v along them as shown in Fig. A magnetic field `vec(B)` is directed into the page. the induced emf in the circuit at any time t is proportional to
