Your friend gets really excited by the idea of making a lightning rod or maybe just a sparking toy by connecting two spheres and making R2 so small that the electric field is greater than the dielectric strength of air, just from the usual 150 V/m electric field near the surface of the Earth. If R1 is 10 cm, how small does R2 need to be, and does this seem practical? (Hint: recall the calculation for electric field at the surface of a conductor from Gauss’s Law.)
