A long straight wire A B of length L(L a, L b) and resistance R is connected to a time varying source of emf V ( t ) . The variation of applied emf V ( t ) with time is shown in Fig. B. A circular metallic loop of radius r=b is placed coplanar with the current carrying wire with its centre at a distance ' a ' from the axis of the wire as shown. The induced current in the loop is
