Question

I posted this yesterday and nobody answered. Will ratelifesaver on this one. I only have one try left on thisone. So any help would be greatly appreciated!
A coaxial cable (like those used in cable TV installations andwith VCRs) consists of a central conducting wire imbedded in acylindrical insulating core, which is then surrounded by anotherouter conducting cylinder usually made of wrapped aluminum foil orcopper braid. Suppose such a cable carries a current of2.10 A flowing in one direction alongthe wire and 2.10 A flowing in theopposite direction along the foil. Use Ampère's Law to findthe magnitude of the magnetic field at a radial distance r= 1.0 mm that is betweenconductors?
