A conducting hollow cylinder (inner radius = a, outer radius = b) carries a current of 40 A that is uniformly distributed over the cross section of the conductor.If a = 3.0 mm and b = 6.0 mm, what is the magnitude of the (line) integral around a circular path (radius = 5.0 mm) centred on the axis of the cylinder and in a plane perpendicular to that axis?
A)50 $\mu$T . m
B)30 $\mu$T .m
C)22 $\mu$T . m
D)37 $\mu$T . m
E)47 $\mu$T . m
