A superconducting ring of radius R has a permanent conventional current I in the direction shown in Figure 23.85 and is

oriented with its axis along the x axis. The ring is moving to the right along the x axis with uniform speed v. Calculate the

electric field (magnitude and direction) at location relative to the center of the ring. If you must make any

simplifying assumptions or approximations, state them explicitly.
