"Gold Nanoshells" are nanoparticles with a spherical glass core and a thin spherical gold shell. They have tunable optical properties, but at the moment consider their electrical properties. If current flows uniformly from the inner surface of the shell to the outer surface, what is the resistance? Assume a typical nanoshell with inner radius 40 nm40nm and outer radius 50 nm50nm. The resistivity of gold is 2.44∗10−8 Ωm2.44∗10−8Ωm
