A rectangular loop of wire with a length e, a width w, and resistance R "straddles" (sits in) two adjacent regions of different electric field as shown in the drawing. The left half of the rectangle is in B₁ and the right half is in B₂, where B₂ > B1. You can ignore gravity for this problem. B. L 80' a. Which requires more force: Pushing the rectangle to the left or pushing it to the right? Or do both pushes require the same force? Please explain in a couple of sentences. b. Which is harder: Pushing the rectangle upward or pushing it to the left? Please explain in a couple of sentences. c. In order to push the rectangle left with a constant speed v, what force must you apply? Give your answer in terms of e, w, R, B1, B2, v, and any constants you need.
