Figure shows five lettered regions in which a uniform magnetic field extends directly either out of the page (as in region a) or into he page. The field is increasing in magnitude at the same steady rate in all five regions, the regions are identical in area. Also shows are four numbered paths along which ∮E .dl has the magnitudes given below in terms of a quantity mag. Determine whether the magnetic fields in regions b through e are directed into ot out of the page.

Figure shows two circular regions R1 and R2 with redii r1 = 21.2 cm and r2 = 32.3 cm, respectively. In R1 there is a uniform magetic field B1=48.6mT into the page and in R2 there is a uniform magnetic field B2=77.2mT out of the page (ignore any fringing of these fields).Both fields are decreasing at the rate 8.50 mT/s. Calculate the intergal ∮E .dl for each of the three identical paths.
