Geometric Mean Radius of Hollow Conductor

  1. Apr 27, 2014 #1
    1. The problem statement, all variables and given/known data
    [itex]GMR_{hollow cylinder}=Re^{-Kμ}[/itex] where [itex]K=\frac{AR^4-R^2r^2+Br^4+r^4ln(R/r)}{(R^2-r^2)^2}[/itex], where R is the outer radius and r is the inner radius, and mu is the relative permeability. We are to determine the numerical values of A and B.

    I am stumped on how to begin attempting this question. Any hints or help would be greatly appreciated.
