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 φ φ = 6t 2 + 7t + 1 where φ φ is in milliweber and t is in second. The magnitude of the emf induced in the loop at t = 2s and the direction of induce current through R are–
