Along straight stationary wire is parallel to the y axis and passes through the point z = h on the z axis. a current i flows in this wire, returning by a remote conductor whose field we may neglect. lying in the xy plane is a square loop with two of its sides, of length b, parallel to the long wire. this loop slides with constant speed v in the xˆ direction. find the magnitude of the electromotive force induced in the loop at the moment when the center of the loop crosses the y axis.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
