A simple and common technique for accelerating electrons is shown in Figure 7.46, where there is a uniform electric field between two plates.

(b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.

Your friend gets really excited by the idea of making a lightning rod or maybe just a sparking toy by connecting two spheres as shown in Figure 7.39, and making R2so 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 R1is 10 cm. how small does R2to be, and does this seem practical? (Hint: recall the calculation for electric field at the surface of a conductor from Gauss's Law.)
