Q. Consider an object with s = 12; rm cm that produces an image with s' = 15; rm cm. Note that whenever you are working with a physical object, the object distance would be positive (in multiple optics setups, you would encounter "objects" that are actually images, but that is not an opportunity in this problem). A positive image distance means that image is formed on the side of the lens from which the light emerges.
A long, straight wire has a 13.7 A current flowing in the positive x-direction. Close to wire is a square loop of copper wire that carries a 2.17 A current in direction shown. The near side of the loop is d = 46.3 cm away from the wire.
What can you conclude about the resulting displacements?
