Question

In the figure the flux through the loop perpendicular to the plane of the coil and directed into the paper is varying according to the relation f = 6t² + 7t + 1 where f is in milliweber and t is in second. The magnitude of the emf induced in the loop at t = 2 s and the direction of induce current through R are(a) 39 mV; right to left(b) 39 mV; left to right(c) 31 mV; right to left(d) 31 mV; left to right

Answer 1

39 mv left to right
