Please solve this question in details and explaination.

The figure below shows two circular regions R1 and R2 with radii r1 = 21.2 cm and r2 = 30.3 cm. In R1 there is a uniform magnetic field of magnitude B1 = 53.1 mT directed into the page, and in R2 there is a uniform magnetic field of magnitude B2 = 77.4 mT directed out of the page (ignore fringing). Both fields are decreasing at the rate of 10.2 mT/s. Calculate o E . d's for (a) path 1, (b) path 2, and (c) path 3. -Path 3 XX .. . . XX .... . .. . . . ....
