Hello everyone i'm stuck on this: 3. [HRW7 30.P.034.] Figure 30-56 shows two circular regions R1 and R2 with radii r1 = 14.0 cm and r2 = 35.0 cm. In R1 there is a uniform magnetic field of magnitude B1 = 50.0 mT into the page and in R2 there is a uniform magnetic field B2 = 75.0 mT out of the page (ignore fringing). Both fields are decreasing at the rate of 8.10 mT/s. Image: http://www.webassign.net/hrw/hrw7_30-56.gif Calculate the integral E.ds for each of the three dashed paths. (a) path 1 wrong check mark V (b) path 2 V (c) path 3 wrong check mark V I did the following: Flux b1 = BA = (.05)(PI)(.14) = .02199; Then i was confused on what I was supppose to do with the given information that the fields are decreasing at a rate of 8.10 mT/s, i saw an example in the book and they divided by that amount so i tried that and got: 2.71495 V which was wrong for path 1. I also tried -2.71495 V which was also wrong. What am i not doing right? Thanks.
