Along wire is known to have a radius greater than 10.0 mm and less 20 mm, carry a current uniformly distributed over its cross section. if the magnitude of the magnetic field is 3 mt at a point 6.0 mm from the axis of the wire and 1.50 mt at a point 20 mm from the axis, what is the radius of the wire?
