n is a positive root of Jv(
n a) = 0. Such series arise in the solution of potential problems in which the application of a finite Hankel transform is appropriate and in which one of the boundary conditions is a mixed one. As an illustration, the method is applied to find the potential due to an electrified circular disk situated inside an earthed coaxial infinite hollow cylinder. This shows that useful results can be obtained provided that the radius of the cylinder is sufficiently large.
