A single-turn circular loop of radius 6.8 cm is to produce a field at its center that will just cancel the earth's field of magnitude 0.7 G directed at 70 degrees below the horizontal north direction. Find the current in the loop.

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
