A metallic rod CD rests on a thick metallic wire PQRS with arms PQ and RS parallel to each other, at a distance $l = 50\text{ cm}$, as shown in figure 13 below. A uniform magnetic field $B = 0.1\text{ T}$ acts perpendicular to the plane of this paper, pointing inwards into the plane (i.e. away from the reader).
The rod is now made to slide towards right, with a constant velocity of $v = 5.0\text{ m/s}$.
(i)[1.0]
How much emf is induced between the two ends of the rod CD?
(a)$25.0\text{ V}$
(b)$0.25\text{ V}$
(c)$2.50\text{ V}$
(d)$.025\text{ V}$
(ii)[1.0]
What is the direction in which the induced current flows?
(a)Along ‘CQRDC’
(b)Along the direction of motion of the conductor
(c)Along ‘CDRQC’
(d)Against the direction of motion of the conductor
